i need something new

I have been playing this game off and on since open beta I NEED A NEW toon. Marauder is the only playable class, for a shit computer, on this shitty lagy game. lock step my ass makes it worse. ... i have try'd to make an UN-kill able lag toon tank, that can afk in front of a boss,/// I don't care if that toon takes 45 minutes to kill that boss there should be a WAY TO make a toon that can't die, even if it takes me an hour to kill a boss... that's a tank...Id also like to see an healer and a control class as well as a well defined dps class... so wee clear... 4 class's dps, tank, healer, control/ support.. so far we have .. dps, support,... and FAIL tank no healers.. fix this crap other wise solo game is the only way to play this.On a mediocre computer with a shity dsl connect... witch is contrary to popular understanding??? the majority of the worlds population has shity computers on a bad connection. pleas fix\\\ all troll kindly don't respond this is for devs.
