Hi again!
Thank you very much so far, your answers are really helpful.
However, I still have some questions that come up while reading:
1)What about Deadly Lunge? Isn't it worth it because it doesn't do critical damage?
2)What about Critical Chance? Don't I need it because of the rubies granting me a sure critical hits?
3)You said that certain gear comes with certain stats. Do you know more about that?
4)If I understood you right, are Proficiency, Critical Damage, Bloodlust and and maybe Concentration the stats I should focus on?
Kind regards
Hello, I'll take a crack at your questions.
1) There are 3 thrusts and each serves a different purpose.
-Deadly Lounge does the Highest base damage of all, but has a longer cooldown (6s). It does not benefit from the Flaming Steel ruby (100% crit under bloody harvest with Rapid Blow and 50% with vicious spin).
-Treacherous Strike is meant to be used on crowd controlled targets for optimal damage. Some might think that you synergize this thrust with the Giant's Swing rubies and Destructive Attack, but there is a translation error which incorrectly calls the debuff a "stun". If you read it it states that cast times and cooldowns of spells are increased for player targets and NPC targets deal less damage. Technically that is not a stun and TS should not benefit from it.
-Rapid Blow does as much damage as TS without the CC proc which would make it the weakest, but it is the only one that benefits from 100% crit rubies. In my opinion that makes it better than the rest(at least for dps

).
2) If you are relying on rubies for crit chance then crit chance from gear is obsolete. Go for Crit damage instead. If your crits are guaranteed then just beef them up

. The Perfect Sharpening rubies increase crit damage by 40 each for a maximum of 120 and I think that gives you roughly 24% crit damage. (I've got 193 crit damage and have 38.6% bonus crit damage. There is a linear dependence in this stat so I can determine the percentage bonus with some simple arithmetic => 193/38.6 = 120/x, where x is the percentage increase. 5 points in CD equate to 1%.

)
3) I'm not familiar enough with this to say.
4) Among all stats Proficiency is the safest bet, because it does not depend on anything to be effective. Here's my stance on the rest:
- Elemental Damage - In my build the majority of the damage is fire so I'll be taking this instead of Physical.
- Physical Damage - From what I've read, tanks benefit from this.
- Determination - It needs to be accumulated first which could be detrimental if you can't get momentum in combat.
- Brutality - I preferred this in the last patch. It tends to make fights end at 25% enemy health. It's okay for bosses because of their higher health pools.
- Natural/Holy - As far as I know, we don't utilize these.
- Double Attack - Might be viable for quickly stacking Cleft Armor debuffs, but you might need to dump
too many points to make it work.
- Fury - Reduces healing. Might be viable for PvP.
- Swiftness - Reduces Cooldowns. This might be very good for bursting.
- Crit Chance - Haha... No.

- Crit Damage - Yes, please.
I personally prefer these stats: Proficiency, Critical damage, Brutality, Elemental/Physical damage
Please just keep in mind that I've tailored my answer according to my own personal play style.
