Thanos Boss Design is so terrible imo.
First of all I would like to say I like the ambition for the Thanos fight. The 15 energy it takes to get to him is probably the best designed thing in this whole quest, but the actual design of the Thanos boss fight is terrible.
My first problem is the cutscenes that play in the middle of the fight. YOU DO NOT PUT CUTSCENES IN THE MIDDLE OF A MATCH IN A FIGHTING GAME!!!!! I can't count the amount of times I got screwed over by the dang cutscenes of Thanos flexing his infinity gauntlet and I died because I thought I was blocking put rather the game ate my input because of the cutscene. Next time please use an ANIMATION not a cutscene. If you're going to do cutscenes only put them at the beginning and end of a fight. No where in the middle.
Someone is gonna bring up Special 3's are basically a cutscene and to that I say you are correct. The thing about special 3's in this game or any other fighting game that has them, if they connect and hit they push you a safe distance away from the opponent and usually have an effect that hinders you enemy like stun or something.
Thanos infinity flex cutscene leaves you in striking distance of Thanos so that last fight where he gets that dumb, stupid Deathtouch BS (which is another problem in of itself because its lazy, cheap game design) you just get absoulety destroyed and you cant do anything about it.
Another thing that makes this boss fight so bad is the reversed controls. I can deal with reversed controls in other games where controls work. In MCOC the controls dont work regularly half the time and then the game team has the nerve to reverse the controls? Seriously? I shouldn't even have to explain how goofy and ridiculous that is.
When I beat Thanos I dont feel accomplished I relieve a sigh and I'm glad that its over. This bosses design, combined with the problems MCOC has had for over months now like dropping blocks, inconsistent parries, dexterity not working, etc, easily makes this one of the games worst designed boss fights imo.
Yes I've seen the guides and stuff on how to beat this purple meathead. But those don't mean anything when core gameplay mechanics don't work.
