ToB is not significantly harder than SoA.

Neither is IWD2 come to that, I suspect most of the apparent difficulty comes from having to learn a new ruleset and of course the different spell list. As for enemies that have more HP than a red dragon - HP dont really matter. I can knock more than 1000 off of anything in less than three rounds, unless its smart enough to defend itself. Which is where tactics mod comes in.
