Who knows how representative of the actual population on green will be. Imo and based on that poll though, we will have too few clerics, monks, warriors, and wizards.
It's pretty hard to have too many clerics, especially for raiding (and pre-clicky-rez raiding at that). Some people are not doing monks in classic because they only want to play monk as iksar, though a dark elf monk seems like it'd be neato. Some people are not doing warriors in classic, especially on day 1, because of gearing concerns on a fresh server. People generally are pretty "meh" about wizards on p99, but imo they'll be in an amazing spot during classic; nukes hit hard as fuck compared to melee damage throughout classic, stuns and roots and snares and quadding are all nice, ports are very convenient especially on a server where not everyone has a druid alt offering to port everyone all over for plat (plus imo druid numbers are lower than usual on the poll too).
But you really can't go wrong with anything if you're getting into this to enjoy the classic experience.
