Ok so lets start with the games biggest selling feature, Playing as those Iconic Z villains. The thought alone of being frieza,cell, and buu hunting your friends was enough to sell this game for most people. However when you actually play they have a " Priority system" A.K.A you cannot play as the bad guy until you play at least 3 human games, those of which last an average 10 minutes. So at minimum you have to play 30 minutes, in extreme cases you have to play up to 6 human games and wait an hour before you can play as the villain. Now onto the villain, in certain villains its almost easy to kill them in their easy stages. All you need is two competent humans and they can easily take you out within 4 minutes. And you'd think that after all that waiting there would be some fail safe incase you disconnect, or the players leave the match. Nope if the server kicks you then you have to do all that waiting again just for another chance. And the game even punishes you when you do good, so as the killer your job is to kill all the survivors, And if the humans just decide to let their allies bleed out those who remain can just get away and they get a win for that.
Now onto the humans. Your job is to set power keys into certain areas of the map, so you need to split up to find all of them in a short amount of time. But the killer can just decide to stay in one area for almost the whole game and wait for the players to come to them. So far there has been no real fix to this other than just hope your teammates understand to jump the killer. But the only way to communicate in this game is with stickers and very limited text. It would be way more efficient if the players could talk to each other through voice chat, or if they wanted to get fancy they could even use proximity chat. But too many times as the human you will see your ally run head first into the killer thinking they can solo them, this game was heavily built around teamwork so that wont kill the killer.
And it hurts because I really wanted to like this game, it was one of the only dragon ball games where you don't just replay the story of Z, and it was a good idea with some love put into it. But after you get disconnected as the killer and get abandoned by your teammates enough times you really start to dislike this game.
