Guild Wars 2

there is no increase in radius between having cannon mastery 4 and not having it.

what is it supposed to do? are cannons currently bugged to always have the radius increase (i think this is likely, but nerfing it by bugfixing only hurts defending more, which is totally unneeded in wvw right now)?

I think it is only a small increase. Wiki says base radius is 360. With mastery my skill description shows 400. I did not notice a huge increase but I thought it was a bit smaller. Need some screens to compare maybe to see how big the differene is.

I think they did not want to make it to big cause with a already big radius only a little bit is already a lot.
