I don't think so, since Mammets/Objects damage is a separate DMG value.
If they wanted to nerf Cannons cuz of Mammets, then they would not decrease damage to Players/Warmachina from 6000 to 4000. Plus with range decrease, you don't need to bother yourself with Cannons if you're using an Opressor.
Seems like they wanted a footsoldiers push(mammets+ healers) to be viable and Cannons to be worthless. It's already a pain to kill Mammets when 3+ healers heal them, pretty much impossible in most random group situations.
TL;DR Opressor can now shoot freely, healers will now push with Mammets and it will be a pain to deal with, Brutes now even stronger in soloing/duo the Core.
p.s. Good thing i got my mount 10 days ago, not sure that i like those changes in RW.
I'l check CE respawn points, though.
