How viable are 5 Druids?

[Anemo]

I haven't played since multiboxing back in TBC and was considering trying it again in classic and was wondering if anyone had any opinions on how viable 5 Druids would be. I've seen that pulling with Moonfire/IS into barkskin and hurricane is a thing solo but not sure how well this could work with multiboxing. I'm guessing 1 feral tank, 1 resto healer, and 3 boomkins could also work even if it isn't as efficient as other comps.

I'm pretty ignorant about classic so not sure how they would do farming dungeons or if stealth running bosses etc would be any good.

Really tempted to try the 5 Boomkin meme squad again but not sure if I can justify the cost anymore. Any input or experience people have that could help or even dissuade me would be greatly appreciated.
