As its first week comes to a close, I think I hate it. Having to chase around jittery players, it having this weird issue with the y-axis when people are on stairs and the like and mastery not feeling nearly as impactful on top of it all.
But ignoring all that, it has some God awful overlaps with boss mechanics. The final boss in Rookery for example spews puddles all over the floor and requires 3 of 5 players to spread out across a wide space, making intercepting the pulsars extremely difficult and potentially ruining what is supposed to be a dps window when his shield breaks.
