I have played with Trick Arrow using it as both a defender primary and a controller secondary.
Entangling Arrow: Not very impressive, but then again the first power in a set is seldom great. Handy for a starter to get double damage as a controller but that is about it. 99% of all defenders will take Ice Arrow I think.
Ice Arrow: Great power. Though some ice damage would be nice I think this might overpower it a tad. Especially since it is a 1:1 (recharge:duration) hold. If it was reduced to 2:1 however some damage would be nice.
Glue Arrow: Great power. One of my favourites so far. Its FX seems swapped with that of poison arrow however and it is sometimes confusing to see who or what is effected. I am not so sure it moves with the original target. Many people say it does, but I havent noticed that so far. All-in-all I think it would do better as a ground targetted power.
Flash Arrow: A bit weak. If it was auto-hit then it would be better and letting the acc debuff last a bit longer would also improve it. It seems to me that as soon as the mobs are aggroed the debuff drops a few seconds later, but I could be mistaken.
Poison Arrow: Another great power. Suffers the same FX issues as glue arrow and would also be better as a ground targetted power. Its FX seems like it would fit better with Glue arrow.
This is as far as I got. I should be getting Acid arrow tonight, which I will be sure to test thoroughly.
