Well that's a question of what do you want to balance based on, hence why i left it as x number of targets. I see what you mean by ratio now, I was wondering where he was going with that (My coffee isn't working yet).
EDIT: I would like to state that the math I used does prove that the ratio of damage stays the same.
4(x)/1.10 + 5/1.10
They are the same ratio as
4(x)/ 1.15 + 5/1.15
However, the off dot pressure is now higher for each target (which was my point). Sure, the rogue now has higher single target pressure but multiple target healing is harder for some healers ( like paladins).
math doesn't work like that. the ratio of rogue damage to warlock damage is always the same, no matter how much you increase or decrease total damage.
doesnt matter if rogue dps is 10k and warlock dps is 15k or if rogue dps is 50k and warlock dps is 75k, the ratio is still the same even if the absolute number is higher.
I don't even know how to reply to this. I just showed you that the warlock's dps will change based on the number of targets and how much damage reduction each one of those targets have as they can off dot opponents. This will change the ratio between rogue &warlock damage as the warlock will always have a higher potential amount of damage possible with more targets. The total amount of damage reduced will always be higher for a warlock in comparison to a rogue once you pass a certain threshold. To claim that rogue and warlock damage ratio is the same at all times is just illogical.
that makes absolutely no sense. if dmg is increased by 20%, it affects every comp equally. in fact, it is a buff to comps that rely on burst. imagine if dmg was doubled, we'd see a lot of triple-dps teams running around because no one can survive their opener, especially warlocks which are not an opener class.
all comps are affected.
here's an example of what i mean
during non burst, a warlock will do 4-5k dps per target &an additional 5k on a single target( note these are just example numbers) and let's say a rogue does 10k single target. it's obvious that for every target added, the warlock will do more damage. it's also obvious that for every damage reduction added for each target (for example 15%), the warlock will be nerfed harder.
multiple target example
4/1.15 (x) + 5/1.15 , where x = number of targets for the warlock
the rogue will simply be
eventually the warlock damage being reduced will outscale the rogue. This would definitely happen during 3v3 using the above numbers. Feel free to post the current numbers but i'm just showing the point.
for every blanket damage nerf, spread damage classes (like warlocks, unholy, boomkin, spriest) their damage reduced can outscale single target classes.
TLDR: blanket damage reductions affect spread pressure classes more than single target.
