Explosive shot hotfixed and nerfed
We made a hotfix recently to lower the coefficient of Explosive Shot. Sorry we didn't get a chance to announce the change ahead of time. We don't typically do patch notes for hotfixes so we don't have a system in place to always broadcast these before they happen.
We are in the process of making some changes to get damage done more in parity (in PvP and PvE). If there are other classes far ahead of you on the damage meters, chances are good they will see some nerfs to their damage soon too.
Overall, we are trying to make changes in a more timely manner so that players won't feel like they are stuck with a bug or other issue forever. We won't be able to get every issue fixed overnight, but it's a start.
