I pulled Harpy Queen like 2 days ago and I just pulled PD. I have, Beast Tamer, Michael, and Druid so I’m just wondering which one would be a better help
I assume you're new to the game.
PD is one of the most important heroes in the game!
HQ lost her place on top heroes a while ago... HQ can be great help, but eventually you will bench her.
Michael is also one of the most important heroes so boost him too.
Druid is a good healer but he will be replaced by ghoulem once you get him. He is still useful in some scenarios (arch-demon and dungeons).
BT is niche hero for rare scenarios - forget about him for now.
I would personally advice you to boost reaper and thunder god (shard heroes) - they are very helpful for f2p players for dungeons (even high insane dungeons) and will be much of help in guild-war when you're still new.
