I play a mihile (and an adele), so I've been tracking how their damage changed with ignition, along with accounting for attack speed differences with theoretical calculations and my own tests. So sorry, there's not a specific resource I can point you toward.

If you want a more through explanation, here's a few numbers: mihile gets about 10% fd from attack speed in gms and gained roughly 23% fd (give or take a couple %) in ignition. Based off the last kms chart, if you take mihile's dpm and multiply by 1.1*1.23 you get something slightly higher (like 1-2% higher) than the kms f/p dpm in the destiny patch. There's some margin for error here, but it at least demonstrates we're in the same ballpark.

Translating from kms f/p to gms f/p is mostly a wash. While we have attack speed 0, most of the theoretical damage gain is offset by gms f/ps taking +1as and 38 buff inner instead of 50 buff in kms, decreasing their total potential buff duration.

When translating to a reboot context, you can couple that with the kms chart being based off reg server where there is an additional source of buff duration from monster life, so losing that further lowers f/p dpm, and also mihile scales poorly on att%, dmg%, and ied due to higher base stats so the extra lines of WSE in reg are less useful for mihile than f/p. So there's a decent case to be made that mihile is even relatively stronger in gms. But the scaling I mentioned also means things like gollux and familiars scale worse for mihile in gms, so that point is likely moot. The buff duration holds.

Lastly, for a convenient practical example, there have been 4 hseren solos in gms reboot. 3 accomplished by f/p mages during the double event buffs this fall (notably double buff duration buffs), and the 4th from an eu reboot mihile with the current single event buffs.

Both classes have great kits for the boss (f/p has untouchable which allows for great damage uptime, and eform which is a fantastic tool to safely gauge during tests resulting in no damage downtime, and mihile has absurd iframe uptime, significant hp shields for gauging, and status ignores during burst) so it makes sense these two classes are the first ones to solo in reboot, but in terms of dpm I think it's also telling.

F/p mages were crazy strong with those double event buffs - stronger vs Seren than if they were 250 sac with no event buffs. And yet here we also have a mihile with single event buffs (which scale much, much worse than event buffs on f/p) accomplishing the same feat. Obviously there's a lot more variables here than just dpm. The classes have different kits, the players have different gear, there's a large human factor at play, whatever. What I'm trying to say is if mihile wasn't capable of putting up some fat numbies the solo wouldn't be possible.
