Remove the cooldown when initiating PvE combat.

That's why there is 10second time to change without CD, so it works in PvE (mined slimes / ambushed by cave lice) but doesn't change much in PvP itself (I doubt it matter for gankers if they have weapon visible or not)

Overall, no. A small nerf or boost to performance in once aspect of combat wouldn't necessarily have much impact to anything at all except in a small percentage of fights. It's the edge cases where the impact matters that you have to be careful of.
