I don't remember anyone complaining about Coil. Everyone loved Coil in comparison to Alex.
Fun, interesting fights which could be beaten without a static if you put in the effort, but still hard enough to encourage having one.
I'd enjoy if Alex became like that, but tbh, it wouldn't save it anyway. Whocareswhatmynameis said it already: there is no real incentive to do savage mode except for enjoying the dificulty (and guess what, the people who do that are unsurprisingly a really tiny minority, others only do it for the rewards). But since you get to play through the fight, see the story and wear the pretty new clothes through normal mode already, there isn't an incentive to do savage at all for many players.
