Good afternoon, I'm at th7 currently with defenses maxed and barb king is level 5. I'm somewhat conflicted as to which troop should be upgraded first, I'm a big fan of hogs so I would like to upgrade them to level 2 but my balloons are level 2, rage spell/heal is level 3, drag/healer level 1. So am I neglecting upgrading more useful spells/troops or just go with hog upgrade which takes 8 days?
Edit: my minions are level 1.
