It sucks. Just a bunch of trials thrown together, except trials are actually exciting. Fighting lol ADS for two turns, or some fanservice elite mobs that don't do anything besides hit for high damage gets old fast.
Caduceus is fun though. Nice scenary and music on T1.

I just want my healer chest from T4 and never go back. I'll not even bother with Twintania, seems like a big bs with bad mechanics and gearchecks thrown in so the few that tolerates it can feel special.
