Microtransactions or No Microtransactions?

For me, the issue of microtransactions comes down to how they are executed by the developers. The presence of microtransactions alone does not make me go: Oh woe is me!

Example: I didn't mind microtransactions in the multiplayer in Mass Effect 3 since it was completely optional and it did not in any way feel like the developers were actively trying to punish me for not using actual money.

Strange, I feel the complete opposite.  In single-player, I'd grudgingly accept it (so long as the devs don't punish you otherwise) simply because others buying their way ahead doesn't affect me.
But in multiplayer, it allows players to buy advantage in a competitive environment.  That's not cool at all, and I'm not sure why it has largely been accepted.

I agree.  I didn't find the the ME3 microtransactions truly invasive.  Plus, it's co-op, so who cares?  But I wouldn't be surprised if it were a gateway to more invasive microtransactions in the future.

It will be there in MP, am almost sure.

But as long as I can find everything by playing the game i don't have a problem.

Why do you think you will need to grind a month or two to get something "decent"? In ME3 MPer you had decent equipment (good enough to do a gold solo if you are skilled) right out of the box. There is supposed to be a sense of progression, and yes rare and ultra rare weapons are more powerful than the commons and uncommons, but the common weapons still killed things and powers could be leveled up very quickly. 

Ideally there would be no microtransactions.

However I can live with something like Mass Effect 3's MP microtransactions provided that we get a decent amount of free MP content out of it, as we did with Mass Effect 3.

This may be an even more unpopular opinion, but who doesn't want their team mates to use RL money and buy up some weapons? Take some of the load off, ease up the kills that the enemy is getting, and we can start kicking some ass.

We live in a age in which simpe smartphone games and f2p moba's make more revenue than AAA titles. That makes it very tempting for developers to introduce micro transactions. Luckily games that do (AC: Unity, Deus Ex) get so much criticism for it, that decent studios won't introduce them in single player. Let's hope BioWare takes the high road (or even the awesome CDPR road with small free updates after launch).

Microtransactions in ME3MP was perfect. There is no need to change it. I spent around 50 bucks on that game. Because I wanted to. I regret nothing.

For Multiplayer, I am 100% for microtransactions, even though I do not plan to spend any money on them. I understand that the game needs some form of monetizing in order to survive and receive updates/new content. Paid DLC is an alternative, but it divides the community and Bioware Multiplayer games aren't popular enough to afford that. Microtransactions are the only sensible alternative.
People who played Dragon Age Inquisition Multiplayer in the early days know that its downfall was due to not having fully capitalized from microtransactions - its RNG system is the worst crap ever, people didn't want to spend money on it. Plus the first (and only) DLC which was supposed to add more content to the game took 7 months to be released. By the time it came out the majority of the playerbase had already moved on. That game mode died due to not having any monetizing potential. I wish Bioware get things right in MEAMP.

As for the Singleplayer campaign, I am against microtransactions but we know they aren't happening anyway, they aren't part of Bioware's business model. Instead of having microtransactions, we will likely be having the usual Alternate Packs/Spoils of whatever paid add-ons.

I call that a myth.

I'd rather say MP had financing for one year of support from the get go. Seeing the gameplay was popular and well received they decided to add one DLC to the original plan. People were eager to work on it because the SP wasn't as well received, but the MP was a full success.

As long as they are focused on MP and do NOT affect the SP then I'm ok with them. Microtransactions keep MP free otherwise people would have to pay for new maps, soldiers, game-modes (I spend my hard earned cash only on SP stuff), also considering the cooperative nature of BW MP I don't see a particular problem if some guys have a better weapons, we are a team.

For MP I pretty much prefer ME3 style with free DLCs and optional microtransactions (no Biopoints this time, PLEASE) over overpriced DLCs.

For SP, as @tzeenchianapostrophe said, NO. Even though I don't really care, possibility of designing games around those is really scary. So, in case they're there (and I fully expect them to be there) I'll do the same thing as in DX:MD, considering ME:A will be any good: I'll be the dude in their corporate spreadsheet who completed the game, including all DLCs, on hardest difficulty, multiple times, who spent hundreds of hours playing the game and who didn't even look at their single players "Cheats'R'Us" real money store.
