Stupidly impossible.
First off, I know it is possible but only if you are rich or perfect. These new quests and act 5 and this stupid unfair uncollected thing. B.s. crystal drops. Been playing for a couple years. 4 5 stars. 3 rank 5 4 stars and no synergies. This is supposed to be fun. It's not anymore. It's supposed to be a fighting game which implies exchanging hits. Not hit someone 38 times. Take half thier life get hit 5 times and die. What kinda **** is that? What makes a fun fighting game is the matches that keep you on the edge of your seat. Plus I have had many many fights where I die and don't even get hit. K have made it to the point where they take off more life when I block them Than I do when I hit them with a special 3. Come on kabam. Make it fun. This is stupid. I get that people have beaten this stuff. But I'm betting there are plenty that are in the same boat I am. Act 4 is beaten. Ideally once you beat a level in a game it gives you the resources needed to at least stand a chance to beat the next on. Kabam spent so much time and energy trying to make the aq issue fair but then you have to fight against act 5 bullcrap.
