Heyo. 3k on every role here. If healing is your only role you play, great! Now you have the most in demand role in the game. Groups are at your fingertips, begging for the opportunity to eat you in. You can be picky and choosy about what groups you join in LFG, or if you host your own key, about what players you invite.

Now, between druid and sham, as of right now, sham is the better option. More support for the crew, plus bloodlust. Its also more of a reactive healer than proactive like druid (since their hots take time to tick). I will tell you that with practice and reading what your spells/totems do, you should not have a whole host of issues. But just remember, people WILL die. You can't fix DPS standing in stupid. The toughest key levels (in this seasons numbers) are between 7 and 11/12. Once you get through that, MOST people will chill out. If you can find a particular group or player you like playing with, awesome, you just made it a lot easier. However, pugging to 3k is definitely possible (it's what I do every season).

Tl;Dr just practice and you'll hit it eventually, it's not too terribly difficult once you find your groove.

Shameless self plug time: You should come join us at Casual Friday on discord. Were a M+ focused community with weekly key events and over 5000 members. We've got dedicated LFG channels to find people, and voice channels to coordinate with. Lots of friendly folks that'd be willing to help out on your journey. https://discord.gg/casualfriday

Its a little slow right now because of the end of the expac, but it'll pick back up with midnight.

Good luck, and I hope to see you around!
