I suppose the value of the debuffs is perhaps beside the point. I’m pretty set on trick arrow over tactical arrow because oil slick arrow seems like a fun mechanic that is fairly unique in the game, which left me with corruptor or defender (or controller). I suppose at the end of the day both are perfectly viable (as pretty much every build is) - I was mostly looking for (for example) pseudo pet weirdness that sometimes shows up in admittedly only some very special cases; or other weird things I just wasn’t thinking about that might bias these powersets to either AT (have not really touched defenders or corruptors since live, and even then rarely).
Thanks for the answers to my perhaps vague questions!
