An issue with multi-classing in classic

[nodoze]

One thing that actually can work, is 4 hunters + a healer. I once leveled a group like that through instances to level 30 something, it wasn't really very difficult, there was so much damage going out that stuff tended to die before the pets got chewed up. The pets just chain taunt, swapping agro, and if they die, you have a mouse over res macro. Healer does what it can.

I don't know/think it's ideal, but, it worked for me in vanilla in an entertaining way. Likewise, a warlock would work as well, as a voidwalker is an even stronger tank than any animal pets.

Did you ever try 3 Hunters and a Druid and Healer (could be a second druid but likely Priest would be better).

If the content is challenging &/or you need a stronger tank your Druid could go Bear.

If a stronger tank than the pets isn't needed the Druid could go cat.

If all were Night Elves you could setup some nice ambushes... You could have the Bear lead chaser(s) like a "flag runner" to the Hunters who then all surprisingly open up on the chaser(s) from stealth. If the chaser(s) react in time and start to focus a hunter or the bear gets into trouble then the Priest steps out of the shadows to CC/heal/dps...
