So, when I say Epic levels, I'm talking about going up to level ~50.
I typically play wizards, and even I have trouble staying relevant. All the advice for making effective wizards assume you're stopping at 20. After a while, level dipping just isn't an option, and it's discouraged by the DM anyway. Spell DC's just don't matter after a certain point, though I realize I probably should be focusing on spells that don't require saves anyway, but still, I'm going to have a few that do.
Epic Spellcasting just doesn't seem worth it to me, am I wrong for dismissing it? If so, how do I make the most out of that feat?
