So during daily roulettes and whatnot I've been noticing other DRGs, and not just new ones (last one was average ilvl 93 or something), spamming RoT on single targets for some reason. I asked one of them why he was doing and he simply said it was "because it's a combo from HT" and that he couldn't help it.

Am I missing something? Did I miss some new information that was found about this ability being used for single targets in the past 300+ pages?

And yes, his damage was horrendous.
