For those on the fence...

I was on the fence too but when they drop the 30% discount I did not resist taking it, otherwise I would had waited till they reveal the CC and LIs.

Which means my final decision would be in early access or after day one but if one of those things sucked hard, I probably would had waited again for some discount to play it just for the story.

I have decided not to buy on launch date and I'm waiting for full game impressions that don't spoil the story.

I may purchase it and play multiplayer while I wait - it's not really a decision I'm making based on whether I want to "support EA" or not as i think whatever problems BioWare's had or are having since ME3 (where I thought they disappointed me) is far beyond any EA-higher-up problem and more to do with BioWare's internal management and priorities.

My reasons are:
A) I do not wish to play a game that has obvious bugs in plain sight on a frequent basis. DA:I was such a game for well over half a year and that's not good enough. There are still obvious programming problems left in the game (like how the quest log plays a sound every. time. you. talk. to. someone!)
B.) If I don't care, I don't care. I've sometimes tried playing a game in a series I was excited about because of story, like Ace Attorney, only to realize I was bored and disappointed out of my mind even halfway into it. Playing ME3 after being really fucking hyped after ME2, I had this annoying, straining, 'forcing myself to play' feeling because I truly did not like large parts of that game. I've since then accepted it and found ways to enjoy it but it doesn't go on my list of top-tier games that I liked playing initially and I think the game has serious flaws from start to finish.
C) If the story is a broken mess, perhaps due to BioWare/Mac Walters not realizing its faults since their plot-writer Schlerf left, chances are fans will point out the mistakes and the game is going to be patched up with DLC story packs later in 2017. If there is an Extended Cut + Leviathan deal this time, I wanna play after that has been made and not before so the magic is dispelled forever.

ME3 and DA:I told me that BioWare needs their fanbase to babysit them in order to make a complete product well after launch. I wanna play ME:A when it's complete. Not when it's obviously lacking extra writing passes and story features that lack resolution or context.

They're giving some explanation as to why Ryder can switch between classes, considering Andromeda is a new story I'm not sure your complaints about lore are fair. 

In my opinion more likely than not it probably comes down to the fact that those on the fence were scarred by the way the original trilogy went in conclusion and just not wanting to be scarred the same way again.

There are other possibilities:

1. Those who wait for reviewers/critics responses as to whether or not it is good and decide from that - most critics/reviewers admonish games I like so... since they don't care I don't care.
   
2. Some who worry that it will be DA:I in space or those concerned that it will be too much like F4.
3. Also there are those who like to watch some gameplay and story done by others before deciding if they will play it.
4. There are others who like myself just hate the stupid origin crap and will wait till they can get a physical copy.
5. There may also be some who try to save their excess money from month to month to be able to purchase the collectors edition.

I'm still on the fence because

A) I really don't know if my PC can handle the game (so I need more input on system requirements. I can't afford to buy better PC pieces atm just for one game)
B ) Like  VanguardianOfInfintiy pointed out I'm not a fan of Origin (and it requires internet connection for use - which is a bit unstable atm at my home)
C) + I really have the feeling to get a mix of DA:I meets Fallout 4 in space (I liked the games to a certain point, but overall they were more like 'meh'-games for me)
D) I really burnt my fingers with prepurchases of games like Battleborn, Lol Men's Sky & Dishonored 2 etc. where the devs lied the hell out of the games and were frankly quite unsupportive with technical problem issues. At least that was my personal experience.
So I stopped supporting this kind of buisness overall.

You can say that I just want to wait and see how everything will play out, patiently.

Probably buy it, the first AAA game i buy at release in 5 years the other one was Mass Effect 3 Collector Edition in 2012.

I can already get Resident Evil 7 for 45 USD, and retailer in Sweden is selling ME:A standard version for 50 USD, i don't need 100000000 extra skins or extra booster packs for MP.

Yep.  Wait for players to actually play through it, unlike the ME3 review fiasco.

I'm not on the fence nearly as much anymore. I preordered the game a while back, even though I had doubts about the game, cause it's a ME game and I like to complete my collection no matter what. I was worried about the mp part, the combat and then the romances too but the last trailer which showed me the combat really put my mind at ease, at least regarding the combat and the previous ones a little bit regarding the romances. I'm very excited about this game and this even though little doubts still creep in the back of my mind of whether it will be good or not, cause again, it's a ME game

I'm not concerned about how Ryder switches classes. I know they said they'll explain that. The issue is I think it's dumb, period. Also I think my complaints are fair. It doesn't make sense these new species can instantly understand races they haven't even seen before. Just because it's a new story doesn't mean they should throw out everything that has been established. It's still ME.  

Real talk: nobody who posts here is actually on the fence about whether or not they will buy this game.

Edit: 

I was on the fence until the gameplay trailer part #1.

Even if the story is crap or if there is a lots of bugs, I know I'm going to spend a good 30-40 hours just doing hilarious things with pull, throw and all the other abilities, along with driving the Nomad into things.

I'm buying this for the same reasons I buy the Saint-Rows games.
