yeah 2 handing is great fun and while you're not some dps-machine its like... you're still pretty hard to bring down AND you do some dps too!
i still normally go sword+board in rvr though, as long as a) the group is competent and b) i actually get some fucking heals (i see so many idiot shamans who spam their crappy dps spells thinking they're some kind of elemental shaman from wow, completely ignoring the fact they can heal. i'm aware they need to dps to keep their heals going but PURE DPS is not the way to do it!! its usually shamans actually, most zealots and DoKs actually tend to do it right.)
if i fight 3 minutes of a scenario and both of those points arent matched i'll just say "fuck it" and whip out my 2hander, run around throwing people off cliffs and kill lowbies. you normally don't get heals if you start with a 2 hander!
if i get heals while tanking, i normally find a good witch elf or marauder and have them stick to me, guard them up and run riot, throwing people off cliffs as i go (i love that. especially in tor anroc where you can throw them into the lava).
chosen gets a bad name from all the idiots who think they're some kind of death knight and run around with a big 2 hander trying to kill tanks. it doesn't work. 2 hander chosen is acceptable if you play it right! in fact 2 hander tanks are good for staying back with the healers and picking off the witch hunters etc. who try to get sneaky kills on them or for hanging just behind the MAIN TANK if you like and holding people off while laying some dps down. and throwing them off cliffs.
i wish i was an ironbreaker cause their knockback is RIDICULOUS
