I recently got the game and only played two rounds of three people games with friends but in both games werebeasts seemed to dominate the playing field. The player had access to so many counter actions and counter abilities that even when two of us ganged up on him from the start he still managed to dominate the field
I have not had that issue playing the game, yes they do get an advantage to speed through the actions, but Seraphim are really good at recycling. Not to mention Elf is also solidly good at using actions without actually using the action cards.
The game is pretty balanced, Yokai are a bit difficult to play with, but overall are also really solid.
