Best single class teams?

[Anemo]

Back when I originally played in 2008 single class teams of all Shamans etc were all the rage but now it seems like everyone is running tank/heal/dps comps. Is this just due to the improvement in multiboxing software, the difficulty of classic content, or something else?

The simplicity of single class teams really appeals to me especially for pvp. I've seen some videos of Dwon running 5 Paladins but I'm wondering what other comps could be viable for various content. I figure I'm probably limited to hybrid classes although Warlocks/Hunters could be somewhat viable.

5 Paladins: Seems great in pvp and able to clear end game dungeons
5 Druids: Managing different forms seems like it would be a massive pain across different clients or maybe keeping 1 bear and other 4 some balance hybrid for damage/heals. Doubt anything other than balance would work in PVP.
5 Shamans: Seems like it would be great in PvP but not sure how well they could handle PVE content. Elemental probably going to have massive mana issues but would 5 Enhancement work for single target DPS?
5 Priests: Might be able to Holy AOE or Shadow to 60 but can't imagine either would fare well in dungeons. Could be amusing in PVP with mind flay tracking targets for you.

Anyone got any experience with these that can provide some insight? I don't doubt any of them can get to 60 but personally I feel like it would be a waste if they can't at least handle the end game dungeons to some extent to be able to gear up.

I have 5 druids and 5 priests alt teams (and 5 hunters too), they are very low so I'll report back when they are higher

Hunters and Warlocks will also both probably work.

I'm up to level 50 on my all hunter team (BM). Solo dungeons up to Maraudon though Mara was tiresome. Heading to ST soon. I really enjoy it the simplicity.

5 priests wont work the rest is ok for dungeon content... in pvp everything works

ele shamans have no mana issues in 5/10 man content thats rather a problem on raid encounters 1min+fights (playing one myself atm)...but yeah you have to reg a lot inbetween fights, I cant wait for the new rank of conjured water comming with dire maul.

if spirit tap procced on death rather than last hit, priests would be top tier.

I ran a group of 5 priests, granted it was end of wrath/pre cata. It was pretty fun.

if they decide to go with classic TBC, i'm torn between priests and shaman. Stacking totems is beyond op and warlocks are dps gods, but TBC priests are more my flavor. With the release of classic and whatever comes next, we are going to have several years of amazing multiboxing and theorycrafting.

I would be disappointed else
