The "confuse" purple set is still moderately cheap (for that type of set), you might look into that for use in your World of Confusion.
I'd personally drop Invisibility and just put that extra slot into CJ for the LoTG. Grab the stealth IO if you really want/need more stealth to stack on top of stealth...but for PvE, Superspeed and Stealth will already do the trick.
With the open power slot you could get Force of Nature for those really tough battles...or you could find another power to drop and go for Aid Self. I see the way you are building for various bonuses, but you can really up your survivability with Aid Self. I'd drop the "Snipe" power...you're much better off spamming Blazing Arrow/Aimed Shot in terms of damage and effectiveness.
yea, i think you are right about the WoC power. I really don't need the extra dmg, but the confuse would be much more useful, thanks
the idea i was going for with invis was to be able to ghost if possible, but i guess, looking back at it now, getting the extra slot on CJ with stealth, stealth itself and SS i should be fine. Maybe even (if i do go down the ghosting route) get recall friend.....
thanks for the advice about snipe as well, i do love the snipe power, but i was playing last night, and realised that i just didn't use it that much, and it was all for show
think i would be more likely to get force of nature over aid self to be honest, something a little different and fun to play
thanks
