I dislike being a 1 trick pony (CP).
I used to play assassin for the longest time until I finally reskilled in the mid 73s to archer and never went back.
Sins have the highest burst damage in game, and are a very cheap class to play imo. There are obviously skilled ones but the vast majority simply rely on their Critical Point to score kills, and I don't want to play the same class as those losers.
A sin is hard countered by dagger defense, and there's a lot of that in EUKO (I don't think you have a jamadar)
A sin must 100% commit into a battle, there's no kiting or backing off because you're a squishy melee class.
A sin's playstyle is repetitive, there are only so few tricks that a sin can use in their gameplay (beast hiding comes to mind), other than that it's just stealth -> approach target -> unleash load and pray to get the kill.
Meh, over time I have come to really dislike that class
