Mark of Blood will be getting 2 stacks of bleeding in all game modes.
Some people complain about this being a nerf, but overall the staff will be stronger after the patch than it is now.
And here is some math to prove it:
1. The damage formula of bleeding
At lvl 80 will be changed from 42.5 + (0.05 x condi dmg) to 26 + (0.075 x condi dmg), so the base damage is going to be lower but the scaling is increased by 50%.
That means with 1500 condition damage 1 stack of bleeding does 117.5 now and will do 138,5 after the patch (assuming you can still get 1500 in PvP). That means 2 stacks of bleeding after the patch will do about 18% more damage than the current 2 stacks in PvP and about 21% less damage than the current 3 stacks in WvW/PvE.
2. On the upside, a lot of features are made baseline.
We get lower cds and size by default, even the 10% direct damage from Spiteful Marks was added, so in regards to damage you will only need to trait for unblockable marks in Soul Reaping (which will be a popular spec anyway) to have the same result as a 4 point investment in Death Magic.
This is a straight up buff for all staff users.
3. Chillblains will get 3 stacks of poison for 5 seconds, now the duration is 6 seconds.
Duration nerf aside, the damage itself is a really nice buff:
Old poison dmg formula at lvl 80 is 84 + (0.1 x cond dmg).
New formula per stack: 33,5 + (0.06 x cond dmg).
If we apply that to a build with 1500 condition damage you get 234 and 123.5 per stack after the patch. That means 3 stacks on Chillblains will actually do 370.5 damage per tick. That is about 58% more damage per tick and about 32% more damage for the entire duration assuming both skills aren’t cleansed.
4. The poison field on Chillblains will be a lot more effective after the patch.
The combo field radius will be a standard 300 units for everyone. Also, every projectile and whirl finisher will stack more poison instead of just adding duration.
For now we only have a few rather unreliable projectiles, but our allies can combo with it and of course once the Reaper/Greatsword comes out we will be able to whirl through as well.
5. Vulnerablity
The change to vulnerablity means a serious buff to condition builds on top of better scaling with condition damage.
For example: the 1500 condi dmg build with 138.5 dmg per stack of bleeding could actually get 173 dmg if combined with 25 stacks of vuln.
As a reference, this amount of damage is currently only possible if you had 2610 condition damage. And a Mark of Blood with 2 stacks of those bleeds would do a total of 346 damage, which is almost as high as you can currently get with the same amount of condition damage and 3 stacks of bleeding: 3 × 117.5 = 352.5.
Bottom line:
In PvP where you have 2 stacks of bleeding already, all of the changes to conditions mean that Mark of Blood and our staff will be buffed.
In PvE and WvW it will also be a buff because we can actually stack condition damage higher than 1500 with full gear and might/vuln stacking in groups, not to mention that our own vuln application will be improved with the Spite specialization.
