Need advice on solo pve build

[Automatron 0]

With solo lvling/questing in mind (so no instance tanking/dps, grouping etc) what would be a good spec?

I'm having fun soloing elite mobs, stealthing past enemies to get quest items, herbs, etc. So with the standard rotation of opening in cat > caster (heal) > bear > caster > bear... this is the build I'm going for:

only indecision is between Feral Aggression / Feral Instinct / Thick Hide.

I really like prowling and going undetected but are those five points worth it or putting them in Thick Hide will allow me better survivability and the possibility to solo mobs I previously couldn't? Then again with survivability in mind would Feral Aggression's buff to Demoralizing Roar give me better chances when being bashed by 3 or even 4 mobs at the same time (plus the buff to FB is welcome even though I tend to use more Rip as a finisher)?

I have the same build pretty much, except instead of brutal impact i have 1 point in Primal Fury

 

So far for leveling (i'm 40) it's been a breeze, anytime I've been close to death healing -> bearform has saved me hundreds of times.

The stealth via Feral Instinct is important for leveling imo, despite having 5 points in that sometimes mobs WILL detect me (Despite me being higher level) if i get somewhat close to them while trying to open from behind, I can't imagine stealth without these 5 points.
