Yeah, but I need a lot of squadmates to actually not get bored of switching them around. I like the variety...
The problem I had was that I never used most of the ME2 squadmates except for on their loyalty missions, every other time it was just Zaeed and Miranda. Too many of the squadmates overlapped with each other, there was no need to have so many engineers or biotics, they could have easily condensed characters.
This is where ME3 improved things, every squadmate had something they were good at that nobody could do better, mind you, this doesn't mean that the squadmates were equally powerful because that is certainly not the case, but they all brought something new to the table, even Tali

. Though most of time I still do find myself gravitating towards the Alliance squadmates, since the Normandy is an Alliance frigate with an all Alliance crew so it makes sense to use Alliance soldiers to go the missions with, especially Priority:Earth.
Exactly.
It was a pointless waste to go that route when there are easier, less wtf-inducing ways than mashing the "awesome button"
Rule of cool took precedence at the beginning of ME2, which sadly, is where the series started going downhill. Bioware shouldn't have killed and brought back Shepard if they weren't going to use his resurrection as a main plot point over the duration of the game, instead, we get a few logs and people act as if bringing someone back from the dead is something that happens everyday.
I have no idea why Bioware didn't just go for the tried and tested coma device. It may be overused in media, but it's overused for a reason, it avoids absolute messes like the Lazarus Project.
