I have 5 upgrades left in my lab: wizards, goblins, rage, and healer.
i never use healers so I'm not even considering it, and I don't want to upgrade a spell.
So which will it be? Wizard or goblin? I don't use either frequently but I was kinda leaning towards goblins cuz I am going to try to finish up my walls soon, and it might come in handy.
I know it's not that big of a deal.. But which should I do first?
