...that I've never played a class to its full abilities. I got the n00b treatment from some when I mentioned a "jump shot" in the Hunter section, but honestly I want to play a character to its full potential and have invested more time into learning more of what it can do. Fun stuff.
As examples, so many times while playing my lock have I noticed mages running to near death while dotted, but never remove a curse. Or hunters never using FD to get a pet off their ass. Kiting a priest or pally is easy as hell now with my new hunter since I've started using Viper Sting. I'm just exploring new ways to make the game fun again...and learning my n00b Horde hunter has been a blast.
All classes get a shit-pile of abilities/spells/skills...but it seems that many only use what's effective in PvE while leveling.
Just an observation.
