Don't need exploits for DC, nor do I use them. For the nth+2 time, I don't use them - though I support them.
Oh, my bad, I forgot after playing since 2009 I should be so jaded that exploits are the only way I can have fun any more. I don't need and didn't ask for char building tips, I prefer to be sat at the back CC'ing mobs, making life easier for the rest of the party, knocking locked stuff before the 2 rogue splash melees can pick it, that sort of thing.
Sue me, I'm lazy, you can have your fun counting numbers on the quest sheet.
