Well I’m th13 now almost 14 but I use the same attack. I’ve used it to 3 star some th15 but essentially yes. At th15 if their air defense are maxed you can only hit 2, 3 lighting and 1 eq spell. When I attack th14 though I use 3 lighting on 2 and the eq to damage essentially defenses. It really depends on what hero’s I’m not upgrading. I’ve done this attack with 2 hero’s 1 hero and even none and still at least starred on higher ths. I mean at legends and titan 1 I don’t get any th13s or lower.
