Oh come now, just because you're frustrated doesn't mean you have to give up so.
It's decent outside of dungeons and very fine in dungeons, nice correction. And thank you for doing basic math, that's how basic AoE's work when they scale more based on even more enemies. I have to be the one explaining that one though apparently.
And? Hit multiple enemies, get more healing. The technicals don't really matter when what comes out is more based on more enemies.
Mainly because there's a cure potency attached along with weaponskill damage, which is quite handy for a tank who has to take damage. Bloodsucker has an innate version of that in Bozja. Also not every AoE has a falloff, this would include this rather neat healing one.
What question? That there's a vocal minority whining about something that's doing pretty good? I mean it's hardly surprising, more surprising is coming from someone that hates to read other threads selectively and yet you ask me to do so when I in fact remember related threads when you love to ask "How is this relevant to what you're quoting, though". No the real question that will come up over and over, is why DRK is behind in the sustain game. It's why well get more threads of DRK needing help, patches to other tanks being a middle finger to DRK, and why the start of this thread began with DRK.
WAR is a great tank, so is PLD, GNB is a bit finnicky but it's still pretty great. DRK is getting closer and closer, but it just needs a little more. However if all people wanna do is try to tear down a nice tank instead of bringing up the one that consistently gets brought up often, then it'll be little wonder that DRK doesn't get much. Enjoy I suppose.
