My general rule of thumb is that if you need to ask if you're ready for an upgrade, you're not. My situation is a little different though. I have maxed out my th10 completely including 275 Lv11 walls, Queen is 40, and going to start my last elixer lab upgrade (goblins) tomorrow leaving only my dark spells to upgrade and my king that just turned 37 and in his way to 38 now. From what I've gathered so far 11 is easy dark (which I will need) but other resources aren't easy. Should I cancel and reset upgrade to finish with King?

TLDR I only have 2 Levels of the king I need to upgrade and my DE spells in lab, should I move to th11 or wait until king will be 40? Thanks!
