I made some calculations today. They're pretty theoretic and based on how much attack% bonus per minute you get by either adding the 5% of poisoning weapon (level2-5) or the whole 5 levels of Shadow Claw.
It's very theoretic and probably far from being accurate, but the difference is still huge:
5% more attack power on the damage from poison weapon means, every 2 seconds you deal additional damage of 5%, if the debuff is activated. Usually, to reapply PW I never need more than 10 seconds, but for the sake of skills usage, let's say we have an average of 10 seconds as a gap.
so one minute is made of
10sec inactive
20 sec active (10x5% damage)
10 sec inactive
20 sec active
that is 20x5% damage, so an average of 100% bonus damage from those 5 points per minute
Now let's assume, 5% critical bonus are bare 5% (let's not count that it's less, because CoA mobs and higher lower your crit rate again based on level, as well as a lot of crits are lost via missing hits. We didn't count it for the chance to activate PW aswell, althought tbh, it's far more crucial to be considered for crit%. So far, every calculation is somewhat rounded up to Shadow Claw's advantage)
Okay, 5% means that 5 more hits under 100 will be a critical, or 1 of 20 hits.
Calculating it via Double Attacks, we have with great haste and vigor rate around 2 hits in 3 seconds. This means, 20 hits in 30 seconds, 40 hits in 60 seconds.
This means, 2 of the 40 hits will be (after the theory of 1/20 hits) criticals. So, you get a bonus damage of 50% per minute.
Of course, not every attack is a Double Attack, but it's hard to calculate damage percentage based on the chance of suceeding with a critical on something else. Let's say, you do an average of 3 1/2 Shadow Explosions and Shadow Strikes per minute. They also take longer than Double Attacks, so let's make the calculation a bit easier for the sake of "I hate math". so 2,5 of the 40 hits are Shadow Explosions and Shadow Strikes. And let's add 5 full Combo Deadly Blows per minute. Best idea would be to sumarize the attack% of all hits per minute.
If 30 hits are DAs, we have a damage of 750%. 2,5 hits are Shadow Explosions, meaning (if maxed) 85x2,5 = 212,5% (let's make it 213%). And 2,5 Shadow Strikes (if maxed) are 2,5x42% = 105%. 5x DB are 5x60% = 300%.
That's (if maxed) All together, we deal an highly theoretic average of 1368% attack power per minute. Now seperating this over 40 hits means 1368/40 = ~34% attack power per hit. This means, 2x the chance of dealing 68% instead of 34%, ultimately, this means a bonus of (again, highly theoretic) 34% damage twice.
So, all together, a 5% higher crit rate nets you the highly theoretic bonus of highly theoretic 68% attack power. And it's a LOT lower practically, since these numbers are not just rounded up but also assume you're not missing a single time.
That means, getting PW from 1 to 5 (4 points) raises your DPS probably a lot more than raising Shadow Claw from 0 to 5 (5 points).
(Edit: BTW Assuming you don't max Deadly Blow, the difference between level1 and 5 are 8% damage. Assuming you're using 5 DBs per minute, your difference of damaged dealed in attack power% are 40%, so 40% less damage per minute if you're using 5 DBs per minute. So yeah, suprisingly not that important at all, but probably not too far from the 5 levels of Shadow Claw, and maxing Shadow Claw still means 1 more point than DB, as you start with 1 point in DB anyways.)
Final conclusion, if I don't max DB, I also wont max Shadow Claw. and before maxing either of them, maxing PW has priority. Still, this is DPS theory only, results differ based on luck and also based on your personal priorities (for example, Colo is absolutely not depending on how much damage you can deal over time)
