1. Nerfing the agility cooldown adventage
If I'm not wrong, max agi adventage gives like 40% faster cooldowns, imo it should be nerfed to like 20%, right now when someone has the maximum agility adventage over you its just impossible to defend from him, if you SPAM defences he can still raise you higher and higher by spamming attacks. An example : attacker with 1000 agility uses kito+flex+kito+flex+kito+flex against a defender with 500 agility that uses sidestep/zigzag. Eventually after a few "rounds" of moves the defender will have 50/40-ish opennings that will result in a very very strong hit AND there is no space for the defender to even try to fight back. If the amount was 20% and not 40%, it still would help the attacker but make it possible for the defender to do anything.
2. Nerfing speed-buffs

Right now when a let's say 4v4 fight happens, one side after losing 1 member will just take speedbuffs and run away, there is no way to catch up to them. I agree that people should be able to run away if they don't want to fight back, but it shouldn't happen 100% of the time.
FIX : Remove speedbuff stacking, reduce spawn-rate of speedbuffs, add a cooldown to picking them up (you can still pick them up while on the cooldown but it only makes them dissapear, so you can prevent attackers from catching up but you dont get another buff)
3. Nerfing bows
Right now bows in PVP are waaay too overpowered. It's literally possible to hit someone for 3000dmg in 2 seconds, and making a character with 3000hp just takes too much time for that to be possible. 1 second of aiming & left clicking a portrait can remove someone from combat completly until he heals. It's nice to have bows around but the damage should be greatly reduced.
