I agree with this. The only difference I have noticed regarding loot is the inconsistency and the amount of nexts required to find good loot.
I have been raiding with BAM as a TH10 thus far and have had no problems keeping my builders going non-stop. My only beef is that some days loot is great, nothing but full or half full collectors every time I search, while other days its the opposite with nothing to be found in storage or collector raids. Weekends are when I have the most time to play and also when loot seems to always be consistently bad.
My actual loot per raid has not changed, even after moving to TH10 a few weeks ago, the only difference is that some days it takes a lot more nexts to find it.
