Hi guys, i wanted your opinion on this ^^

I'm a th11 with maxed walls and heroes, i still have to upgrade :
2 air defenses, 2 wiz towers,and all the 2 bomb tower, archer towers, cannons mortars and swepper

I'm still missing some research in the lab, but i already maxed out miners and that's mostly what i use.

I was wondering if i should upgrade to stop wasting elixir and dark elixir or if i should wait and finish more defenses
