I have fully maxed defenders, all walls maxed, both heroes maxed. The only thing I have left to upgrade is my lab. In my lab I have the following left to do:
Haste Spell
Skeleton Spell
Bat Spell

I am wondering if it is worth upgrading to TH11 without maxing these as I no longer have any use for gold, any use for elixir when goblins are done and only need dark elixir for troops not heroes. All builders will be idle within the next couple days. What should I do?
