Can someone explain to me the difference in the different professions/classes for the game? Like how is an engineer different than a ranger, necromancer different than an elementalist or mesmer, or guardian different than a warrior or reverant? I tried looking on their website and it doesn't really explain the differences other than like a mesmer makes clones but so does a necromancer (well sort of since necromancers summon undead which is similar). Reverant isn't even on their profession listing and the description of both warrior & guardian doesn't say that they are a "tank" or "dps" class just that they are strong in using weapons.
