We picked up
[Formula: Enchant Weapon - Blade Ward] so I figured I'd test it out. As a new enchant in 3.1 and having not seen this discussed anywhere else, I decided to post it here. My question from this was really "how good is 200 parry rating that is up 10% of the time?" and how does it compare to Mongoose for an avoidance set.
WWS
Hits: 1229
Crit: 44
Glance: 323
Total Hits: 1596
Procs: 23
Procs resulting in a stack of 2 or more: 3
Estimated proc rate 1.5%
No ICD as evident by parses below.
35 minutes of white swings 3'38'' uptime on Blade Warding or roughly 10% uptime.
Each stack procs 200 parry rating and a 600-800 damage return on next parry per stack.
Sample from a WWS Parse on Yogg-Saron:
4:41'27.062 Abso gains Blade Warding. #828944
4:41'32.268 Abso gains Blade Warding (2). #829306
4:41'34.862 Abso gains Blade Warding (3). #829542
4:41'36.699 Abso Blade Warding was removed from Abso. #829866
4:41'37.109 Abso Blade Warding hits Guardian of Yogg-Saron #182 for 3686 Physical.
The three stack is a 600 parry rating buff and 1800-2400 damage on next parry. The high damage seen here was due to the guardian buffs.
The gear I was testing tonight had 118 parry rating on it, bringing me to 17.06% parry (including DR). Using Whitetooth's numbers, it takes 49.18499 parry rating = 1% parry chance, before diminishing returns.
Ignoring diminishing returns, it would look like:
0 stack: 17.06% parry
1 stack: 21.126% parry (gain 4.066)
2 stack: 25.193% parry (gain 4.066, net 8.132)
3 stack: 29.259% parry (gain 4.066, net 12.198)
4 stack: 33.325% parry (gain 4.066, net 16.264)
5 stack: 37.391% parry (gain 4.066, net 20.33)
Obviously, this would be far too high and we know it won't work like this.
After diminishing returns, it looks like this:
0 stack: 17.06% parry
1 stack: 19.83% parry (gain 2.77)
2 stack: 22.24% parry (gain 2.41, net 5.18)
3 stack: 24.34% parry (gain 2.1, net 7.28)
4 stack: 26.21% parry (gain 1.87, net 9.15)
5 stack: 27.87% parry (gain 1.66, net 10.81)
So far, the proc rate seems alright and the uptime is decent enough. The interesting thing with this enchant is that with seemingly no PPM, it scales well with haste. I'd be curious to compare uptime with Windfury or Improved Icy Talons.
