WoW - Any reason when levelling alt accounts to not just make all Demon Hunters (or if capped) then DK's?

[Kojiiko]

I rerolled servers and tried to create 4 Demon hunters but I need a level 70 on each account to do so, instead of not thinking I created 4 hunters and 4 druids (them account still have RAF) then mixed them up so I could level up in dungeons but then I thought about just boosting them with my 5 account which is actually alot faster.

At level 70 I could create 4 Demon Hunters but I had the same problem about trottleing bullshit, just wait a few hours and u be able to create more Demon hunters, just keep trying a few hrs or.

Demon Hunters Veng (tanks) OP I just have them on the server running in highmountain farming foxflower, Ill log on an hour a day and just farm and kill or them crabs giving be my bloods from the shoulder enchant, then Ill go buy the fjarn herbs.

The only problem now is that Im addicated to leveling up toons, with 6 weeks left of RAF I still need to create some hunters and druids on the horde side >.<
