Ideally you would want animations that while satisfying, don't obscure or distract too much from what's going on so that you can better react. The more you can view, the more the developers can ask of you, the higher the skill ceiling.
What we've seen fails in my opinion, on both accounts. Even at low levels with 4 people it's a weightless light show -imagine this with 8 or even 24 players.
