I've gotten several compliments for play as well as for name / bio / concept, and it always feels good. I try to do the same and will frequently send a tell when I see something I like. Probably the one which most stands out is from Live, and it stands out now for being an unusual thing to be complemented for. I got complimented on my skill using Teleport. And I don't mean a clutch Recall Friend. I mean Teleport. We were fighting mobs on multiple bridges and I TP'd from the lower bridge to the same spot on the upper bridge to help some teammates. Note that the bridges were directly one on top of the other, so there was no direct line of sight. The thing that impressed me was that someone actually noticed this.
Plenty of toons have uber builds, but it's the players who show great awareness and strategy that really impress me.
