My solutions/ideas

Witch OP:

Personally, I leave witches & their skeletons alone for now. I think we need updates; such as, mortars, infernos, xbows, and teslas first. Then on the offensive side, I think upgrades to loons and drags would also go a long way in having attackers utilize different attack strats at the TH11 level. If people are still going with mass witches and destroying Th11 after those defenses mentioned above are upgraded, then it's probably time to nerf it.

The loot/where's the loot:

At first I hated being forced to put my TH inside the core. Trying to figure out the best hybrid to use has been a PITA but the adjustment so far has been smoother than I thought it would be. I grew up (on this game) tossing my TH to the outside, chilled behind the shield, or attacked and lost the shield. I also farmed with barch taking out the mines, collectors, drills and if I was able to get stars (so be it) and if I didn't (oh well).

But to add to the economy, I recommend adding another mine, collector, and drill... then at TH11, give mines, collectors, and drills another level. (we all know the 1-Gem boosts are helping the economy some, but it's just a band-aid).

PBT:

Personally, I think it has to go. But since it's not going to be going anywhere, anytime soon, I think it has to be consecutive as opposed to cumulative. And I don't think being raided should/shouldn't matter, just be booted for 1/2 hour or 15 min and the PBT should just reset. As many guys already noted, what if you're in a super tight war and then the PBT prevents you from getting an attack in? I know in my clan, several guys wait until the last half hour to get their last attack in for either cleanup or whatnot. It's a strat that worked for us for sometime now. Being that we're in the holiday season, we really haven't warred anyways, so PBT hasn't affected my clan just yet. With that said, I recognize the issues others been having.

Overall, the last update wasn't as bad as some made it out to be, but not that great either. The only positive I saw coming out of the update is being able to attack and not lose your shield.
