Dark Knight changes needed

[Nektulos-Tuor]

For 30 seconds every 90 seconds, meaning a 33% up-time versus a potential and preferable 100% uptime for Darkside and Maim.

So ((0.85x2)+(0.85x1.3)/3)= (1.7+1.105)/3=0.935

Which equates to a slightly higher overall damage multiplier than the other tanks, but balances out with other factors such as more offensive OGCD abilities, DA buffed attacks, etc.

So in the end they are close but just slightly behind in dps compared to the other tanks when MT.

Yes, but remember you can use it when you need to. Like when you switch to Sword oath for a short period.
