its really a bad idea for people that try to play pvp more often to not get frustated when they punished by dying from getting permastunned or instakilled.

stuns have too short of a coldown for when there is only one cleanse and timing guard its not possible most of the time because of lag, the cleanse coldown could be lowered instead, or the stun resistance added, or stun duration lowered specially short coldowns one like War Primal Rend.

Insta kills are fun only for those who dont get it, specially when most matches tend to be defined by the first group fight because limit break is so influential, with a ton of new people to pvp people get to stomp then really easily while their other members may be better yet they get punished by letting a example: Samurai build their limit break which ends in them oneshotted without any counterplay other than Guard, and lag being a major problem in most non jp places makes it frustating.

regarding Premades: i feel the insta kills and stuns should be resolved first but there is another solution to implement for premades for it to have Role Limits, so people cant stack Warriors or Dark knights etc. so people get to play with their friends to have fun and people cant abuse the pvp, I would love to play with my friends just some casual matches or even get into ranked because of it.

otherwise, pvp is really fun when you are winning.
