You didn't read my post properly. I think Katsuni was happy with Memb's success and I agree that Katsuni never seriously tried to make $ out of AoE. However, based on the comments he made during his streams back then I am pretty sure he was very unhappy with Memb joining escape, and there is every reason to believe that this led to great tensions between the two. Since Katsuni isn't very active anymore we will probably never find out the details (I wouldn't believe anything memb says about this, memb is really fond of whitewashing). In any case, my point still stands: it takes two and memb was one of them. He certainly wasn't always fair to everyone, as some of his fans like to think.
Actually, like more than a year ago, I even recall that an arena tournament was around, people frequently asked Memb why he didnt co-cast with Katsuni anymore etc. bu got no clear answer. So I and other people asked Katsuni on his stream why he didnt co-cast with Memb anymore and he he exactly said something like ''it doesnt work when two works and only one gets money '', this may not be his exact words but it is the exact context. I dont know if they had an additional breakup because of Zak but as mentioned above, that's why they didnt co-cast together anymore.
