TH9 also... currently focussing on Heroes as I've only got two upgrades left for structures (DE drill to 6 and one skelly trap to 3). Walls all legos, will upgrade to lavas as I have idle loot but won't focus on them.
For those that are late stages/advanced - do you recommend upgrading heroes by staggering them, or one to the next ability level then focus on the other to the next ability level?
For example, upgrade BK from 13 to 14 then Queen from 12 to 13.... Or do BK all the 15 and then focus on getting the queen to 15?
TIA
