I don't believe in Tiers, DM's should just decided if They don't want it in they're game or not. "Tier" doesn't make a difference in that, unless they just look at that and nothing else.

Neither do I ever look at other classes to "Balance from". I make classes spontanously when the idea comes to me. I don't sit down and stare at the Rogue all day and compare feats. Planning? I don't know the word :/
