Making TVHM worthwhile

So farming mayhem 3 on normal isn’t difficult anymore and I can get get numerous legendaries from slaughter shaft if I want to do something more entertaining then boss running. The problem is Im now hunting for annointed legendaries and if increasing the difficulty guarantees more anointed drops then I’d welcome mayhem 3 on TVHM. At the moment TVHM doesn’t give enough incentive to want to play on the hardest difficulty and I feel this is a great fix. Also it would be great if we have another visual cue to when items are annointed.
