Restrictions for when and where flame rams can be built in wvw.
1.) They must be within reasonable distance of a gate
2.) You cannot build them at fortifications you own
As popular as flame ram “art” in keeps are, I don’t think they contribute positively to the wvw experience. To be honest, I think this update has been long overdue for a while.
Yes, I know that ballista “art” is probably going to replace it, but at least ballistas cost more and can conceivably have a valid use in a keep.
