A couple of players I play with have expressed concern (after seeing the contents of Hero's Call), that they will not truly be uber when they reach Rank 5.
I can't say I disagree with this much, though my players are still Rank 2 so we haven't really playtested it yet. Just looking over the abilities and such it doesn't seem like a character rank5 will be TONS more powerful than a rank1. You can still only use one action per turn (in most cases). And while there is some modest increase in power for some classes, others get very little (it seems).
Does anyone else have this impression? Has anyone else reached Rank4/5, and can you give some feedback as to how high-ranks play?
