Game Mechanics: Safefall & Sneak/hide

[AimAce]

Lvl 35 rogue, after the last patch I've noticed I have some serious issues with safefall. When I fell from large heights I used to take maybe 6-10 damage max, (Towers off LoIO) and now I frequently take over 80 dropping off heights perhaps half that length. Is this an issue?

Furthermore, when I am successfully sneak/hidden, I notice I am sometimes aggroed by nearby mobs every now and then. This is a *non combat* successful hide, and I don't recall sarnaks having see invisible. Can anyone confirm deny?
