You're really not understanding the build... Im not talking about ticks... I'm talking about bleed stacks. Each Splitblade throws 5 blades... each one causes a bleed and has a chance to proc your traited crit bleed and your sigil bleed (that's 15 bleed stacks if they all proc). Each tick of Hunter's call has a chance to proc the traited bleed and sigil bleed (24 stacks of bleeds if they all proc since Hunter's calls has 12 separate ticks of damage that each can crit). None of that is counting your auto-attacks (which have a chance to proc 2 bleeds per hit) or sharpening stones.
Please click the build, read the traits and the weapon skills.
There is no mesmer build that comes close to acquiring this amount of bleed stacks (or any other bleed build for any other class).
Bleed isn't about stacks, it's about ticks. The only time the actual number of stacks matter is if you're already hitting the max 25 stacks, or if all the stacks are such long duration (I usually go with > 10 seconds) that a wipe becomes likely. Otherwise it's more productive to simply look at how many ticks of bleed you actually inflict. Let's look at your build
I'm going to assume:
70% crit rate
2 Sigils of Earth
Bleed trait is 33% chance to bleed for 5 seconds, same as the warrior's
Auto-attacks occur once per second
2x Sigils = 84% chance to bleed for 5 seconds on a crit = 4.2 ticks average per crit
Trait = 33% chance to bleed for 5 seconds on a crit = 1.65 ticks average per crit
12 hits from Hunter's Call -> 8.4 crits -> (7.056 x 5) ticks of bleed from sigils + (2.722 x 5) ticks from trait = 35.28 + 13.61 = 48.89 ticks per 25 seconds = 1.9556 ticks/second
5 hits from Splitblade = 3.5 crits = 30 ticks inherent + 14.7 sigils + 5.775 trait = 50.475 ticks per 6s = 9.125 ticks/second
2 hits from auto-attack = 1.4 crits = 5.88 sigils + 2.31 trait = 8.19 ticks
50 ticks from Sharpening Stone per 45s = 1.11 ticks/second, 2.22 ticks/second with rechargeTotal ticks = 21.4928 ticks/second
Now a mesmer with a staff and Sharper Images and 2x Sigils:
2 hits from auto-attack = 1.4 crits = 4.62 inherent (33% chance to bleed for 7s) + 5.88 sigils = 10.5 ticks/second
6 hits from clone attacks (three clones) = 4.2 crits = 21 trait (100% chance to bleed on crit for 5s) + 13.86 inherent = 34.86 ticks/secondTotal ticks = 45.36 ticks/second
As that clearly shows, the mesmer bleeds more than twice as much as a ranger does on average. The ranger can spike more bleeds at the beginning with Sharpening Stone and Hunter's Call but then output drops substantially while everything is on CD.
In fact, I could do this for all the classes if I had the time. That would end the debate pretty conclusively.
