How bad are the issues with DRK?

[Eliroth-Kaminari]

TBN is the DRK equivalent of sheltron and inner beast, but also have the utility of "Intervention". You have the choice between using it to protect someone else(utility) or yourself(defensive cd).
The sheer number of skills may be lower but wont change how they can be used. TBN costs a single Syphon Strike worth of MP meaning you can always have it up for a tank buster as long as they are at least 15 seconds apart.

Issue is moment someone cover 3 pld skills whit TBN.
u earlyer mentiond TBN replaceing loss of repaisal.
THen u mention TBN is equivilent to shildron and IB
and then u mention intervention.
Witch is it then.
Because TBN is single skill whit 15s cd. Not 3 skills whit 15s cd.
