I dont post much anymore. I used to post stronger builds i created and found fun, they would then nerf some aspect of it slightly hurting the build but destroying many other builds that needed that aspect to barely be viable. This made me feel like an ahole, the collateral damage on others was too high and i felt partially responsible, the devs and perhaps their egos (offended by the fact that some player was using abilities in a way they hadnt considered) were primarily responsible.
Many of the nerfs were irresponsible, for example things of medium impact would be nerfed where many other things were drastically overpowered. Often things would be nerfed and the reasoning would be severely flawed or some shortcut would be applied rather than fixing the real problems. This is the case with offhand versatility.
Offhand Versatility prenerf made many different builds possibly, from tanky closeup casters weaving melee and spells to fast moving charging intermittent melee aoe burst to glass canon builds using a destiny tricks to melee at range and nuke from relative safety.
If offhand versatility was nerfed due to the fact that long duration damaging buffs or dots were critting for the entirety of their duration the correct fix wouldve been to address the fact that the spells dont roll for crits on eact tick, this would also adress the problem of super low damage on dots due to them almost always not critting for their entirety.
I cant think of any other reason to nerf it, its addition to the game went a long way toward dealing with the problem of mage survivability vs melee survivability, it offered a choice of higher damage at greater risk, it also allowed for many hybrid builds that could not work without it.
Ive seen a lot of bad nerfs over the years, this one is hard to beat. The 1.5 sec thing seems insane as well, but i assume its a bug.
