Nice to meet you Gavaroc. Just a pity that for every one like you there are twenty out there who are pretty much the poster kids for "annoying".
Things that annoy me when online? I have an anecdote. this happened to a friend of mine, who is a very competent Guild Wars player. Like, REALLY competent, this guy owns. His necro/mesmer build is terrifying.
Anyway, he's fairly casual about playing. Mostly he prefers to do the co-op storyline missions than get stuck into the PvP, but occasionally he'll drop into a PvP team arena and look for a team to hook up with.
Recently, a team he offered to join told him to pop up his signature or something (I forget the exact term, it's the "pro" way that people are advertising themselves as good PvPers, apparently). When he said he didn't have one, the immediate response was a flood of "lol noob" from pretty much ALL OF THEM.
These guys were all cookie cutter builds - IWAY warrior/rangers, 50HP monks, that sort of thing. to their way of thinking, there is one and only one way to play the game - the "pro" way, invented by some other, greater player who actually had a goddamn brain. Never mind that this necro/mesmer build my friend uses absolutely destroys IWAY builds, never mind that he's an exceptional player of the game... because he doesn't use a "pro" build or have this record of every fight he's ever won, he's an automatic noob.
And of course, he can't begin to BUILD this record of every fight he's ever won because none of the teams will take him because he doesn't HAVE this record of every fight he's ever won because he can't begin to BUILD this record of every fight he's ever won because none of the teams will take him because he doesn't HAVE this record of every fight he's ever won because he can't begin to BUILD this record of every fight he's ever won because none of the teams will take him because he doesn't HAVE this record of every fight he's ever won because... ad infinitum.
THAT is the sort of stuff that truly annoys me in games. This prescriptivist "only these select few builds, tactics and behaviours work, the rest is noob and not pro go learn 2 play noob." attitude.
