Those are class type designators, though.
So you have [Heal][Tank][DPS], as if “I am/can Damage Per Second” makes any more sense. It’s more like “I’m Heal spec” or “I’m geared to Tank” but everyone drops off the fluff for quick and easy match making.
Not to mention party name character limitations make “LF someone with a class focused on healing skills” out of the question.
It’s different from casual conversation where you’d expect natural language. If you’re talking about your experiences, you might want to choose words that actually mean what you want to convey, rather than nonsense or practically the opposite.
If you dropped gear, doesn’t that mean you lost it? Sorry to hear you dropped that rare bow, but maybe you shouldn’t have clicked Yes on the prompt? Try locking your important things so you don’t accidentally drop them next time.
