Lego (and potentially lava) farming
I've just finished upgrading my defences up to max for th9, only one more archer tower to finish. So I've decided to start Legos properly and heroes. I'm 22 Legos down, feeling okay, BK going level 13, AQ is 11 (decided to work them in 5's).
Regards to walls, how is best to farm them? I was thinking do half Legos, then farm a lava core, then finish Legos? To mix it up a bit? What are others experiences? I don't expect to finish lavas before going to th10, I reckon I'll get bored, but we'll see. Any advice is welcome, otherwise I wouldn't be asking :p
