[2021] Undocumented Mid League Nerf to Hateforge

This change was a result of us discovering that Ballista Totems could keep using Vaal Rain of Arrows and Vaal Burning Arrow with Hateforge with no limit at all (as they ignore all costs, which was never tested because it was assumed at the time that they worked slightly differently), but as far as we could tell nobody was doing this build (and it requires no investment other than owning the gloves). We decided to change it quickly before it became known, but by no means should it have been changed without any warning or patch note. I'll have to investigate how this happened.

We weren't aware of the trap use case, and it's definitely not something we'd want to change mid league. We usually only nerf something mid-league if it far outclasses anything that is otherwise possible (like the unlimited Rain of Arrows) or give unlimited damage or damage immunity. I'll look into having this changed temporarily to only apply to totems for now, as soon as we can deploy the restartless change. Though that's not an ideal long term fix because the description would be inaccurate or very lengthy, but this should re-enable the legitimate builds until the next league if the change is possible.

The patch today won't be able to make a change, it will just be properly describing the change in a patch note, but I'll update here as soon as I have an answer about what's going to happen next and when.
