Yeah, the odd high lvl TA troller does exist 
I have an earth/TA slowly crawling to 48.
And yes it's definitively worth slotting damage. Currently i have it slotted: 3 recharge/1 def debuff/2 damage.
Not really convinced wether the def debuff is worth it, hard to find decent info about TA. Need to do some careful testing myself, but im probably gonna swap it for a 3rd dam.
The dam is slow DoT with many ticks, but in total pretty good. (silly enough the dam it does isn't registered in the combat screen and doesn't give you orange numbers, but the kills are counted as yours though -how weird is that?) So you want to shoot it of first thing and hope it'll be ignited asap.
Yeah, as far as I could tell it was ticking grey 3s and 4s at level 35. Nothing in the combat window. I don't intend to try slotting the def debuff, I don't miss much anyway, and I would imagine Acid Arrow gives more -def for your money.
I really should do something about this signature.
I assume it does much less def debuff then acid arrow indeed. The debuff isn't even documented in the description i think, its just you can slot it.
Thing is that the AoE of acid arrow is much smaller then oilslick so a def debuff in oilslick would affect a lot more mobs. As well as the nature of the power is diferent; any mob walking/knocked in the slick gets affected even after casting, where as acid arrow is a one time hit.
Also the def debuff is not only meant for you to have a higher hit chance, but also for your teammates ofcourse
IIRC, the def debuff is a mistake - it doesn't actually have any -def effect at all. It was removed before the powerset went live.
(I haven't answered this previously as I don't have the slots to spare to test - my oil slick is only slotted with 3 recharge atm)
"I know 653 ways to kill a man. Fist to the face is #56."
Oooh good to know. Thnx for that WE.
*goes out to quickly snd slots a 3rd dam instead of def*
Have a TA/Arch def since they were introduced and after all the different variations I tested, it ended up being 3 recharge/3 dmg as the best way to slot this as said above.
Just thought I'd confirm.
-Quiller Queen-
Is it worth slotting damage?
(didn't think it was worth posting this question on the controller boards, as I don't know of any higher level /TA controllers than me).
I really should do something about this signature.
