Most likely has to do with lore. Since Worgen are essentially cursed, it'd make less sense for them to be Paladins than Taurens

bet blizz doesnt want 2 make worgens 2 popular sides they got the druid class seems enough for them

No, it's definitly lore based. A worgen (which is the result of a curse) fighting in BG, casts remove curse on himself fighting a lock and BAMMO, no more worgen. But I'll be the first to admit it'd be badass lol.

^ Paladin's can't remove curse, only magic effects, poisons, and diseases.

Hey guys just wondering, whats wit no worgen paladins? Is it something with the lore, or did Blizzard just decide not to go there?
