If you’d like a comparison, I’ve successfully made a Pierce Vire’s Might Dervish which uses most of the same pieces as your build: lots of PSP damage, Vire’s Might doing a lot of legwork, and nothing complicated like attacking in the middle of Vire’s Might.
However, where my build succeeds and yours doesn’t is that my Vire’s Might build uses 40+% CDR and multiple small heals like Dryad’s Blessing to ensure that it could handle multiple hits + keeps Ascension and Ulzaad’s Decree to a reasonable uptime that you can rely on it when you need it the most.
This build has 0% CDR and most of your flat damage is Bleeding, meaning that even if you rush through a crowd of enemies, there’s not a lot of flat damage you can leech off of. This is not a knock on you in any way; this is a core weakness of the GoreDrinker’s set that I pointed out in the “bitch” thread when the set was published for the first time and the testers didn’t sufficiently address.
There is also MysteryMeat’s Physical Vire’s Might Warlord - which also doesn’t have a lot of attacking for sustain, but uses CDR, small heals, and damage mitigation to protect itself in tough battles.
With low CDR and little in terms of good Weapon Damage abilities to make good use of the ADCTH, there’s little I could suggest that would tangibly help your build. The concept of “Use Word of Pain to whittle the groups down while charging the rest to keep your Health up” is a neat strategy, but it fails compared to, say, banana_peel’s WoP to Blade Arc because Blade Arc is providing tons of leech every second, while Vire’s Might is a more active skill which only leeches the one time you rush through an enemy.
