Warcraft 1 elves were priests. They should also be priests and mages as well (after all they were highborne outcasts from night elf society). I would take warriors off, as the original blood elves from Burning Crusade expansion weren't warriors. The blood elves also learnt the paladin way after abusing the light powers of a naaru, so I would cut off paladins as well.
My feeling is that the closest high elves are to plate classes are spell breakers (warcraft 3):

So i would make the following classes:
- hunter;
- rogue;
- monk (any race can learn monk, as long as they are friends with the pandaren);
- priest;
- mage.
Possibly death knight.
