I for one appreciate Anet being strict about naming policy. This is an RPG, god forbid you have to make an actual ROLE-PLAY name. I think WoW has just jaded me to this, because they let you get away with all the stupid ass out-of-character, l33t d3wd names you want there.
That said, sucks for people who miss out on the headstart -- next time read the naming policies :)
Not everyone role plays though. What if you PvP only? Even if you're doing PvE, there should be no requirement to role play. I personally think RP names are really cheesy. There should be no naming conventions in a video game. Only overtly offensive names should be banned (racist, homophobic, pornographic, etc).
If you don't want to take part in an RPG, why bother playing an RPG? MMORPGs are persistant online worlds where the setting and lore has had years of manpower and money put into it to make it as engrossing as possible and people who want to get into that shit have every right to. So if ArenaNet wants to ban people who are ruining that experience for them by seeing someone named "Ballsachs McPwnsauce" then they can go right ahead and ban those people -- good fucking riddance, I say.
Also, I don't RP and never have. But I don't go around thinking I'm less nerdy than the nerds who do like to RP. We're playing an MMORPG, we're fucking nerds. Get off your high horse and read the EULA and policies.
Also x2, this isn't directed at YOU, just a general rant I have on the entire situation.
