I am interested in elite mob damage (not bosses specifically, the elite trash) in instances.
My interest is in trying to nail down if mob swing timers (or internal cast cd's though that is a much harder one to quantify) are identical to classic.
This is a simple math exercise and the major challenge is getting vintage videos which can provide useful information.
videos from 2.0 to 2.2 for classic dungeons should provide dungeons which are essentially untouched from 1.12.x
2.3-2.4 are the first blanket nerfs of dungeons, and damage is expected to change both as a funtion of mob level changes and actual nerfs. I am not sure if swing timer were increased on any mobs, though.
3.0-3.3.x would also be of interest, if for not other reason than to compare.
I don't know how a person is going to get accurate swing timer measurements down to 1/10 second from old videos.
I know considerable work has been put in on demonstrating that, when locatable, elite trash damage integer numbers appear functionally identical (after backing in appropriate approximations of buffs, armor, etc) to those in the beta.
I feel this is an equally interesting area to investigate. For example - if swing timer in the beta are a few tenths of a second longer, that is a pretty big net dps impact vs. players. Perhaps blizzard is using information from current state of retail classic dungeons to inform swing timers? Unlike vintage video dissection, retail vs. beta would be a very, very easy comparison, relatively.
Lots of angles to compare are possible.
