Issue with TBN

[Shurrikhan]

If you severely overgear content you don't need the shield and can just use the MP on flood.

So what? Every other tank at that point IS getting free mitigation from their equivalents where you'd then have... nothing. Having TBN isn't balanced as a trade-off with damage; it's balanced such that TBN has limited use events, limiting it towards HoS/RI/ShT. But, by fundamental design that limiting mechanism can make it utterly unusable without tankbusters without losing damage, which creates a far larger blow than DRK is balanced around.
