i'm having the beta on two of three devices and like it. Both the fix enemies plus character limitation give the game a new edge. All players that hoarded their characters and kept them and not sacrifice them (like me) have now a lot of better chances to get the higher ranks. I'm on rank C on one device and can't continue as i have no more magus or warrior eddies left. Also this will bring a lot of gold draining, as you now have to level some talismans just for the sake of having a certain character of a class fully equipped.
I mean before, you had your teams:
1 PVE (mainly a good AOE eddie with leveling characters)
3 for the dragons
1 or 2 LOL Teams and
1 or 2 PVP Teams (maybe matching against prisoners)
and now you may need:
5 Teams of Magus/Warrior and maybe other combinations, too
