I saw some players complaining about cancellation. I play as Soul hound, but I understand that cancel sucks in a pvp, cause cancellation in l2 was made for official buff time, when you aways is with a buffer in your pt. Here, with Buff 1 hour time, its not always that you have a buffer to rebuff the cancelled buffs. Some servers use a system of buff that you can rebuff using communit server (Alt+B). Since npc buff dont have all buffs, I think that it's not a problem if we could rebuff using alt+B even outside cities, if you're not in a combat mode, of course. Cause Its not fair take cancellation and dont have how to rebuff, but nerfed classes its not fair either. Mystic muse, Arch mage, Soul Hound, Hellknight, Soultaker, healers, summoners, many classes have cancellation skills (and there is pvp daggers/fists and hero spears too), but usually only Mystic muse, arch mage and Soul hound are nerfed, thats not fair. So, thats my suggestion about cancel, Alt+B buffs when you're not in combat mode, fair for everbody. :D
Im saying that because Im sure that soon or later somebody will make a post asking staff to nerf cancellation skills.
