The new 100AL armor gave me the idea of making a high hp build, or, so to speak, a "tough nut to crack"

Here's what I have so far:
W/Mo
Str 16 (12 + 1 + 3)
Sword 10 (9 + 1)
Healing 9
Skills:
Defy Pain (elite)
Endure Pain
Dolyak Signet
Berserker Stance
Leviathan Sweep (make sure you hit those annoying rangers)
Healing Breeze (or I Will Survive / Purge Conditions on condition-heavy areas)
Vigorous Spirit
Live Vicariously
So with high AL and 1000+ HP this is a difficult char to kill. It won't deal as much damage as a sword W, attack as many opponents as an axe W, or block everyone like a stance tactics W, but it's just a different build conception

One of the doubts I have with this build is the following: how much Str should I have?
16 Str (or 15 Str)
PROS:
- Lots of extra hps with Defy Pain + Endure Pain
- Can constantly keep Dolyak Signet up
- Big bonus to all str skills
CONS:
- 75 health taken from sup rune (50 with 15 Str - Major Rune)
- Lots of stat points spent to get Str to 13
14 Str
PROS:
- No HP loss from superior/major runes
CONS:
- not such a huge bonus to str skills
- shorter Endure Pain time, and less hp bonus on Endure + Defy
Also, would Mo be the best seconday for this? I have considered Rt for the +hp weapon and Necro for the +hp spell. Also maybe Elem for armor + conjure weapon (water) or wards (earth)
TIA for your opinions
