Question concerning Regen

[Nihil1ty]

So I was chatting with someone in EC today who is very seasoned on p99 and they had mentioned that there is a nerf at some point to Iksar regen.

I was curious if this is something that comes with Velious or a later patch? I actually rerolled from DE to Iksar weighing the benefits of regen for necromancers and found it was worth it, but if it IS nerfed at some point I don't want to weigh that into my decision and was also just curious in general. Sorry if this is posted somewhere, I couldn't find any information on it.
