Has someone run the numbers on Jom Gabbar for a rogue? Combat sword specifically, although I'm also interested in combat dagger.

Other random questions:
- Does the trinket benefit rogues more than other classes?
- How much more dps will it offer over earthstrike? What about a Hoj (in a long boss fight vs trash pulls)?

Thanks in advance for any info.

it has a cooldown of 2 minutes, and 20 seconds of uptime, so you're getting pretty solid AP value over time with it even by itself. additionally, if you can stack other attack boost abilities with it (blade flurry, rapid fire, etc), you'll get pretty huge returns. i'm looking forward to picking one up soon to go with my 3 minute rapid fires from striker's garb - if i use jom gabber and rapid fire at the start of a fight, and the trinket again as the cooldown comes up, i'll have it ready for a third use right when my rapid fire is ready again, which seems like it will put out some pretty sick numbers.

Timed trinkets like earthstrike and this one will likely generate more damage than passive ones like hoj or blackhands due to the fact that you can combine them with other timers. Any physical damage class can really take advantage of it well since you get so much return out of it when you combine it with things like rapid fire, death wish, blade furry, adrenaline rush, sweeping strikes, recklessness or other similar options.

I expect we'll see some sick hits near the end of this trinket's activation affect, maybe even some pvp videos with nu metal!

There's some discussion on it here. It should answer most of the questions you have. You can also take a look at the rogue dps spreadsheet for the other trinkets you've listed and compare them to the dps of your optimal attack cycle w/ Jom. Your dps mileage will vary based on how much +hit, crit, +skill you have.

I'd say it's equally useful for any physical damage class, but every class may need to change their special attack cycle in order to min/max it (e.g. a warrior will want to bloodthirst on the last tick and work backwards to determine other optimal times to bloodthirst when figuring out their cycle, etc.) If you're willing to burn AR and/or a thistletea it can have a nice burst at the end.
