Skills retain as you delevel?

[Crazrum]

I think on live you could keep your combat skills from 2 levels above your level, but you could not use spells or abilities if you weren't of the level that you received them. Example: if a monk deleveled from 31 to 29, he kept his 1hb skill (160?) but could no longer use flying kick. If he deleveled again to 28 his 1hb would become 155, etc. I seem to remember playing a melee in PvP a long time ago, and we always got 2 levels above the level we planned to stay at to max our skill caps before deleveling 2 levels.

This may be completely different on P99 though.
