On one of my servers, I run a big plugin that hooks reload, primary attack, primary attack post, and take damage. I was wondering if it's possible to not even look at those if they don't have certain skills (unregister the HAM hook if they do not have a certain skill, per player basis).
It seems that a lot of data is being sent to them even if they are lower level or level 0, since it's hooking their attacks for everything. I do check for their levels right at the beginning, but I'd prefer it to not even have to check (or only check once) if it could be done.
