What Classes do you wish you had more of?

With the crazy fast leveling going on during (WoW's 15th Anniversary) inside "Korrak's Revenge" BG, I'm thinking of leveling up some more toons. I'm sure you are too. Now that we can have 50 toons all on ONE server, I got room (on the servers I play on) for more toons

I five box ali and horde. I have one of each class level capped. (level 120). Many classes I have 5 of that are level 120, for example I have a team of 5 mages. So lets make some more teams and level them up.

Should I make 3 teams of 5 mages OR 3 teams of 5 Druids? OR should I do 3 teams that are 1 tank 1 healer 3 dps?

What Classes do you wish you had more of?
Which teams / classes would you pick and why?

Just remember when shadowlands hit lv. from 0 to max. is about 70% faster that it¨s to day. Only 1 expansion zone is needed.

A team of druid farmers - my druid team is set up for gathering

I need more of the classes I don't really know how to multibox well at all. Rogues (and Cat druids), Priests, Warlocks and Mages are the ones I struggle with most. Rogues because of the combo point system and casters because hunters have basically ruined any other class for ranged capabilities.
