How is this fair for DRK?

25 seconds isn't a short cool down compared to TBNs 15 second cool down.

Also, TBN has a much shorter cool down compared to the other tank defensives because it has a cost.

This is Balancing 101, very basic stuff. And yet, it flies over the heads of pretty much everyone on this forum.

yes TBN is shorter but is also still worse than other 3 in many ways
Blood whetting is 25 seconds but you really only have to wait 17 seconds to get the healing effect again because that last 8 seconds

There are other uses for TBN that just tank busters, uses that do come more frequently.

damage is not that frequent to where TBN extra 10 seconds will actually make much of a difference especially with HoC and Blood whetting
