My thoughts on this update:
Lab upgrade order: 1) healer5, 2a) wall breaker7, 2b) miner5, 3) wiz8, 43984) pekka6
I'm intrigued with how useful miners will be once you factor in their hp buff, miner5 and L7 heal spell. There's potential here.
Return of the hogs! They're already useful for 11's bullying 10's and poorly designed 11's but very few clans do this. Can't imagine how good the buff will be. Cliff is already licking his chops. On the flip side, goodbye air at 11vs11. The loon nerf last month added to this update's AT and inferno buffs make air next to impossible for 11vs11. Witchy-bowl takes a hit too. 10's uphitting on 11's took a major hit.
A little surprised there's no additional L12 walls. I thought for sure there'd be some with the launch of wb7. 100% L12 walls are inevitable. There's enough to do already in this update with the new defenses and labs. Adding more walls in a later update is a good way for SC to milk some more $. I'm still convinced that every troop/spell will get a TH11 lab eventually. After this update, the only ones remaining are goblins, valks, lightning, rage, jump, quake, haste. None of those move the needle other than rage, not sure how they could squeeze that one in. L5 haste seems like a easy solution to buff air in a future update.
Updated time needed to max the lab at your TH level (estimated the TH10 time reductions in update): TH10: 337 days, TH11: 298 days
Not much for non-TH11's. Maybe a boost for suicide dragon raids, or hogs for a 10vs10 solution if a kill squad can get the cc, AQ and an inferno. Nothing for culdeus either.
