So I understand people saying it works with thorn. Theres multiple issues with that however. Yes, its powerful [i]with thorn equipped[/i].
In content like raids you tend to run exotic heavies or other such important exotics. An exotic kinetic that isnt izanagi's has next to no place for raid encounters. This same principle tends to go for high rank nightfalls as well.
What people are asking for is not a buff, but a fix. The exotic has a very clear description stating:
"Damaging combatants with melee attacks corrupts them with increasing damage over time. Defeating a corrupted combatant spreads the corrupting effect to nearby targets [u]and restores melee energy.[/u]"
It currently does not restore anything. And due to bungie having locked out multiple exotics this season already, one can assume that its synergy with thorn is entirely intentional, and that the gauntlets do not, in fact, function as they should.
They already said...it is supposed to function with thorn.
And the melee energy does go up if you melee an enemy that has the gauntlet poison effect on it.
