Hello guys first of all i am not new to wow i've been a wow fan player since the start of cata , i had a shaman with almost 120 days game time. i heard all the fuss about vanilla being good so i wanted to check it out and i found it really interesting so my question is which class could fit with what i want ? - i don't like the 2 - 3 abilities and you're out of mana and you stand still doing nothing for the next 4 seconds and i hate very slow casting. - got a hunter to 10 but then dropped playing him i didn't like hunters , i also love horde so i won't play paladin since they are only ally side ( I am sorry alliance players but for the horde)
