You’ll probably never be the main tank where it matters, so taunting will only make the main tank angry. I find it useful only when the main tank dies and let’s face it, when he does, it’s very likely you’ll die even faster as you are not a fully fledged tank.
18% evasion bonus is nice, but again you are an off tank, not being attacked most of the time, but swordsman’s c2 buff restrain gives you 20% chance to stun monsters, so in aoe situations it’s way more useful, 20% procs all the time since you are using multihit attacks. What’s stunned doesn’t attack nor run away. Combine it with dmg buffs and you have a winner.
Regarding DPS, there’s literaly no evidence proving swordsman is lacking in DPS, just a bunch of folks here on the forum that yell korea this, korea that, but when you ask for proof… nothing.
And even if that’s real, there are class balance changes in every patch in every mmorpg, so what’s not perfect today might be tomorrow.
Also regarding hop c1, Stabbing is an amazing skill even on c1, finestra gives you like an equivalent of 50 dex + aoe, so that’s really good.
