I've not yet started any serious thinking about cat DPS in 4.x. On beta I'm at 5.4k (on dummy, MotW, not using berserk in the rotation), which is a sick joke considering that I can do 7+k dps on live being 5 levels and 50 ilvls lower. For me, this means that a lot of work must still go into feral. I'll wait and see.
I hope that we don't end up with the "refresh Rip during TF only" which seems to be the current trend. I find interesting to manage DoT uptimes, and this just takes it out of the picture.
BTW napkin math shows that in the current scenario synching TF and rip is a loss: Rip lasts 16+6 = 22 secs, TF has a CD of 27s with the glyph.
If you synch you end up with 11 rip ticks every 27 seconds. If you assume that your rip ticks do D damage and you have 30% crit your total damage every 27 seconds is: D * 11 * 1.3 * 1.15 = 16.445 * D.
If you don't sync and keep 100% uptime you end up with 13.5 rip ticks every 27 seconds: D * 13.5 * 1.3 = 17.55 * D. So a constant Rip is better then a TF-synched Rip. Of course it costs you CP to refresh, so it'll be a matter of seeing if you have something better to do with those CP.
I'm continuing developement of RWF, with a big twist: since 4.0 will be going live soon, I'm killing WotLK compatibility and the next version (0.2.0) will be 4.0-compatible only. Since there's not much theorycrafting around I'm removing most of the "error" indicators until the situation settles (I'll keep the "melee without SR" and "Rip/FB not at 5CP", mostly). One big change is energy regen being haste-linked: this means that unless I have the haste rating + all haste proc info, energy regen wil be incorrect.
I'm taking advantage of the time to also clean up the code a bit. After cat Cataclysm compatibility I want to add tanking, which means tank health tracking, which is a mess. But I already wrote it once, I should be able to survive a rewrite :)
