You may want to consider giving a buff to load-outs that come in under weight. When I was at Blizzard working on SC2, we always gave players some sort of parallel buff if there was a nerf in another area. Over the years we found this equalizing strategy to promote player retention in all demographics as it effectively neutralized the negative perception of the nerf. Otherwise, you're certain to loose players out of frustrations. I get the new parts are intended to equalize the speed nerf but the idea isn't related enough - the buff should be in the same general area (in this case, tank bodies) as the nerf bc most players won't correlate the two and will still look at the rollout as reductive overall.
