Blade And Soul: a decent dps class with a few utility skills

Wrong forum and probably a clickbait title. Anyways, assassin in BNS isn't very ping-reliant. For PvE, it is a decent dps class with a few utility skills. They tend to not be very popular in parties because they do not provide much compared to other classes. Sin probably shines the most in PvP because of their counter skills. They tend to have difficulty against classes that can easily pop their stealth or immune their stuns like Summoners, Lyn Blademaster, and Destroyers.

Okay, since rework, their dps increased and they are a bit more ping reliant. However, they still hover just below the top tier dps. (top dps being Warlock, BM, KFM, and FM)

I don't main one, but I've talked with some people who've played them, and they seem to be solid in pve and pvp, not OPed or anything, but definitely not terrible. 

You may be watching the pre-rework videos. After the sin revamp, they are much more fun and more Cheap Blade And Soul Gold. For the most part, they are a dps class with back-up utility. They can block ranged projectiles with smoke screen, pull party members to safety, and AoE stealth. I guess one of their main con, similar to KFM, is that they focus on single target damage (all classes can AoE and single target, you just have to respec skills).
