As someone who has played with weapon swapping a lot I agree with this post. I don't understand the viewpoint of those saying it should be increased further. There are many disadvantages that come with the weapon swap CD and can make pvp a pain in the ass for people. It's also the fact the the weapons attack speed retain their original cool down even after the weapon swap. What I mean is if you use a Bone sword which is .5 second attack speed and melee then swap to a pipe which is about 2.5-3 second attack speed you would have to wait the seconds before attacking again, which is fine. But why stack CD's like that.
Also in the past weapon swapping was never broken, there wasn't even many masteries to use it honestly. People just complained about gf/wm but swapping cool down was never a problem for a gf wm with a nerf or without. Not many were weapon swapping alot in the past and the ones that were didn't have the ability to even use the new weapons which would make swapping more viable. Like pipe didn't exist and etc... I don't think it balances much, like in the post it says it ruins combo potential which is true and hybrids need that since pure have a huge advantage with fortitude being the highest stat value
