If I'm going to be frank (not Frank, that's my dad), I really have no idea what WanderingAries is doing with this character. Says it's a primarily offensive, but power choices are very weird. No Hot Feet on a primarily offensive character? Really?
And then the slotting is just silly. Defense IOs in Stealth? Really, you really want to increase that (approximately) 2.5% defense to 4.something percent? That approximately 2% extra defense is really going to make that much difference? ONE recharge in Fortitude, plus slotting tohit and NO defense?? Recharge in Ring of Fire, which is already only a couple seconds recharge?
It really, honestly, looks like you went "I'll put one of every possible IO in each power, that looks about right." Note: it's not right.
WA, I recommend taking this build back to the planner and doing some serious tweaking.
