We all know SC dislikes troop spam and mass attacks instead of nerfing everything into the ground can they just limit the housing space per troop to a max of 120 per army at th10/11 (not counting CC troops)? So for example you could only bring 4 golems in army, or 10 witches if they mattered anymore, 15 Valks, etc.
May create issues with milking or all arch, but 50/50 barch would still be a viable option.
Only real issue I see is drag attacks, but if SC is not in favor of mass attacks this would go a long way to solve the issues.
I think SC is cool with mass drags. Decreasing the variety of attacks possible isn't really a good idea imho, so I don't see this happening, without maybe increasing the limit of course...
