Seems pretty rushed. Sure, you might have maxed towers, but you don't have max troops, max barb king, etc
AND MY EYES HURT JUST LOOKING AT YOUR WALLS ARRGGHH
It's not really rushed... all elixir troops and spells are maxed for th8 but the dark troops are just level 1
Also the reason I didn't upgrade the walls is that I feel walls are over-rated... I mean, it cost 25mil to upgrade all lvl6 walls to lvl7
Anyway $30 for this account is pretty worth it... a maxed TH7 costs around $25 - $30 and a max TH8 cost around $50 - $60 and my account is basically TH7.7
