Using Smoke Grenade is a very, very bad example because as you pointed out Smoke Grenade is terrible.
Also, looking at One power is a mistake.
I'm saying if my Trick Arrow is on a team, let's say there's also a Dark, a Storm, and a Poison on the team, my Acid Arrow will improve many of THEIR debuffs, which have much larger values to work with than Smoke Grenade.
