I never felt that Breakneck was particularly overpowered in any aspect, but upon using it in the new sandbox, I saw that the damage with each stack of rampage is noticably lower than before. This is most likely due to a combination of the rpm change and the decreased damage that rampage now does in PvE. Granted, this change doesn't take place in PvP, but I still feel that it wouldn't be particularly game breaking if Breakneck's rampage stacks performed the same as they did before. So far I've been enjoying Shadowkeep and look forward to all the new stuff Bungie will unveil this season!. Any feedback would be appreciated.
