I am a TH9 with all max defenses and buildings. the only things I have left to upgrade are walls, heroes, and lab. I only have minions, valkyries, and the de spells left in the laboratory. Would it be better to fully max out TH9 with level 30 heroes and all lava walls, or, to have all defenses maxed, all lego walls, maybe some lavas, with max lab and heroes to level 20 or 25? Need feedback on when to upgrade to TH10! Thanks :)
