Ok, so a better explaination, for what i have been doing and having reasonable ease with leves and stuff is this,

For HP Regen -
Have life surge at 3 stacks at all times - you can keep this controlled with Invigorate when out of battle without TP.
Second Wind - pretty much the most important cross class skill for soloing in my view, at 32 it restores around 250hp
Bloodbath + Blood for Blood with WS - not as good as it used to be with doomspike but can still give back around 150hp.

Stunlock combo
Using Heavy Thrust ---> True Thrust gives the enhanced stun effect. After your True Thrust hits, you will see that your moves that are able to cause a stun status will glow pink. You can use these free from TP charge and if a stun procs, the stun duration is significantly longer than normal. This can be insaine if you leg sweep a large group.

Conveniently Heavy Thrust is also a stun proc move, so you can use it as your free TP move, stunning one target, and then you are able to just throw a True Thrust and complete the Combo again.

If you are carefull on your cooldowns, and manage Heavy Thrust with Keen Flurry you can just continually use the stun combo to semi-stunlock your enemies and hit free WS damage.

This is working for me in low-mid 30's and can only imagine its the same futher on.
