Using Only Alien Sidekicks

We don't even know the characters yet. Maybe the human companions outshine the alien ones this time. You never know.

I plan on doing multiple runs with different combinations.

I'll stick with this combo for as long as I can.

But the Turian will be replaced by one of our Androman sidekicks the moment I get em.

It feel weird to not use an Androman.

Drack will come along everywhere with me.  Other people's loyalty missions?  He's joining

For my first playthrough (will be playing as male Ryder), its going to be Vetra 100% of the time (she looks as an amazing candidate to replace Garrus) as my first squadmate and as for the second squadmate... it will be either Drack (will be useful to help with "harsh negotiations") or Liam (he may turn out to be an actually interesting "Jacob").

But truth is, everyone of us should pass the game enough times to get at least 90% use out of every squadmate in all the plot situations in the game.

Bioware says background for all of our squadmates is very developed this time around, so there surely will be a lot to learn about them by interacting with them via banter / R&R / missions.

Different suqadmates you take along on a particular mission could have noticable impact on the outcome of that mission, I'm very intriqued to find all of that out:)

I really find it hard to say without knowing a little more of them. If there's a companion which I like much more than any other (like Garrus), I usually take him/her with me everywhere. Then, there are companions that I like a lot but that usually feel a little wierd to bring with all the time, because they're suppossed to be doing something else and kind of important (I feel like this with Mordin pre-horizon in ME2 and Liara in ME3) so, actually, for RP reasons I may leave them behind more often that I'd otherwise. Another thing that usually factors in who I take with me, particularly in a first playthrouh, it's who seems to be more interesting for a specific mission. And after all that , I still think about who matches better my PC in terms of powers (I don't worry about this in ME as much as in DA, but I still do). All that said, I usually lean towards alien companions

Well, if my track record is anything to go by, I will definitely have an alien only squad.

My favorites to bring along for the trilogy were: Garrus, who was a permanent member of the squad really, followed by Tali, Wrex, Legion, Mordin and Javik on rotation depending on the game and mission.

So far, I will definitely being giving Drack and Vetra a chance. There's supposedly going to be a squadmate resident to Andromeda, so they will most assuredly be given a chance as well. Liam sounds interesting enough, so if I wind up liking him, he'll be the first human character to break my all alien squad since ME1.

I tend to like alien squaddies more so it's possible, but depends really on how good the characters are.

Based on my play history, my first run I'll likely have my LI with me all the time and trade out the other slot until I develop another favorite, then bring them everywhere too. On replays I'll do rotations so I can hear/see more of everyone.

I really wish MEA companion will complain to PC if He/she not pick them to go do mission for a while (lost friendship too will be good).

To answer question, my answer is NO. If I have to choose between All human squad / All non human squad, I will choose All Human Squad without hesitate.

BUT Personally, who I choose to come with is base on their skill & how they relate to mission. And I have admit that I will bring my guy with Scott as much as possible.

Nah, I do that overall too, it's just on my first run I tend to have my LI and other favorite with me all the time; while the LI part is intentional, the other companion just seems to happen. First time around I seem more likely to forget to switch out parties. Not sure why. I tend to do a lot of replays though, so over 2-3 plays I've usually had a go with all sorts of combinations. In games like DA with banters, I still discover new ones later because I apparently made a particular combination for the first time at the right point.

It took me a few plays through ME1 to get that achievement, and I only got it because I had my LI at the time with me while I did all the sidequests - I wasn't even actively trying to get it. 

Depends on which companions I end up liking the most though at this time I am hoping that the alien companions are fun to drag around. Most likely I'll just end up switching people in and out until I find a team I like the best then almost never change that. Unless there are achievements that add to the game for taking certain companions around like they had in the first Mass Effect.
