Bioware would have to change gameplay somewhat to make it more balanced if this was option. I don't know if it would be easy to do or if it would take sometime. Also wouldn't the system have then to be similar as in Dragon Age- when PC falls down you control squadmate who revives others?
You wouldn't have to switch to control of other squadmates. In Halo 5 you don't, and in Republic Commando you didn't (blast from the past). You just sort of sit there. I agree that you would think that enemy damage, numbers, or something would need to be different relative to if player couldn't be revived.
I felt that the revival thing in Halo 5 made the game way too easy compared to prior Halos. Sure, I'll be the first to admit that it was incredibly convenient, cut down on annoyance deaths and made gameplay more fun. But it also dumbed down gameplay a bit too...so I'm torn. My first reaction is to say no - I like Mass Effect's gameplay the way it has been.
I didn't actually play Halo 5, actually 3 was the last I played. I did beat CE and 2 on Legendary, since they are available on PC. In any case, it seems from watching bits of it (and some of the other ones), was that they made it relatively easier to kill some of the alleged mid-tier and higher enemies however you wanted, which was something of a departure from the first two.
I think there should be certain squadmates that could heal others but not all of them. I remember that one of the abilities in ME1 was medicine, I think Kaidan had it, not sure if anyone else had that ability. It would be interesting for a squadmate to rush over when the AI senses that one a team member is about to die.
Yeah, in ME1 Sentinels were supposed to be sort of like medics (or healers), at least according to flavor text. They did have the Medicine talent, but so did Engineers (unlocked Neural Shock power).
