This. Also... people still highly undervalue the first move you get in DW tree. It is EXCELLENT for spamming while tanking (and does fair dmg when maxed). I don't know if they changed it from KR but I used to use this ability to deal damage very quickly to a lot of mobs as a primarily defense based DW, and on KR the dmg was much worse too lol.
Anywho, the whirlwind ability is good when used with the reduced CD powerup because literally by time you're done the animation (with reduced CD powerup) you're ready to use it again. If you're getting hit enough, you're generating more than enough RP to spam it nonstop (and even if you're not, hello shiny RP potions), and with high enough defense and health you really can grind non-stop with big aoe pulls (minimum of 7 for efficiency) as a fully specced DW tank.
SK have better threat because they do big damage and bleeds, but they have weaker defenses, do not have a reflect ability or that huge buff that sacrifices LP and adds a large amount of defense.
Heirgo, a DW will always have MUCH better defenses because in order for an SK to also be able to tank well, and enjoy their class outside of said role, they must invest into damage skills (Whether how many they need or not, Idk) whereas the DW can avoid any and all attack abilities if he chooses (Whirlwind really is all you need) which opens up room for much more defensive capability.
