We have been provided some lists of changes, but it is not that easy to figure out what they mean to the larger Clash of Clans meta as the issue is quite complicated. However, the Archer Tower and the nerf to Cannons, on the defensive side, make it way easier than how it was pulling off a successful Queenwalk. It is not the first time Supercell pushed to nerf the strategy. Goblins and Barbarians have also gotten a lot more useful with their HP buff, and if we take that into consideration, you will figure out that a shift in army compositions will be potentially spurred by this over the next few weeks.
