I might have mentioned this before, but the current numbering scheme really is misleading at best. I'd prefer if it were just descriptors IE
Great
Good
Even
Bad
Worst
Or something like that.
There's also the fact that a +2 tiers PrC turns a tier 3 into a tier 2, not a tier 3 into a tier 5.
IF I have several days off in a row to fully and categorically complete my book collection, I'll see about doing a massive thread for all of this, kind of like a quick and dirty build list for as many base and prestige classes and combos thereof as possible. And if possible, put the top of the food chain in the first reply post (i.e. Druid/Planar Shepherd, SCM, Incantatrix, etc.).
