What ticks you off and sends you into a swirling inferno of anger and frustration?
For me it's when random people check you in town and then comment on your gear. Now don't get me wrong I don't care about /checks, infact I check a lot of people myself but when they go out of thier way to mock your ENM or BCNM or SOLO gear or subjob it pisses me off >_>
Take for example when I used to level drg/whm, I would get a lot of checks concerning my gear and how gimp it was. Now when I play DRG/WHM usually I'm just trying to solo a few more xp to level up, or just looking for a change of pace. For this reason I take off most of my Acc gear and replace it with MP gear.
So next time you see a strange subjob/equipment combo there is no need to try to enlighten the player to the conventional choices
Sorry that's my server-down rant for the day
