Guild Wars 2

Guardians, Elementalists and Thieves have have pitiful amounts of hp, barely 10,805 without vitality gear, meanwhile Rangers, Engineers and Mesmers have15,082 why is there such a huge gap between tier 1 and tier 2?, dont you guys think the game will be much more balanced if the devs close that gap a little?.

mesmer 15k health, necromancer 30k. meanwhile thief and guardian 10k.
