This actually caught me off guard because I know for sure I have my Skada set on Effective Time. I checked other vods from other kills and it's showing the same thing, acting as Active Time. Double checked all my accounts' Skadas and they're all on Effective Time, but I reset the settings just in case it bugged or something, because it definitely shouldn't be working as it is.
You're padding on ghouls. I can tell you on one hand how many times I've used MS in phase 1 since beginning to farm it nearly 3 years ago.
Not bashing, just pointing out that it doesn't make sense to cut a tank and/or healers if you're not going to play around the increased DPS. Having watched your vod a couple more times, I guess you guys weren't going for speedkills and was just doing a spicier normal kill, which, hey, if I played on Icecrown I would be down to do too. I just don't understand the reason of cutting tanks and healers if the goal isn't necessarily killing LK the fastest you can, but rather making it arbitrarily more difficult for tanks/healers for seemingly no reason. At least with a proper speed comp kill, P2 lasts for one, maybe two valk waves; in your VOD, with only one person dead, your DPS is barely better than ours and you play the same number of Valks. Of course the target prioritization and class value when building a comp for 1 tank/3 heal vs 2 tank/4 heal is different, but the outcome is nearly identical, except it's harder on healers and the tank.
Funnily enough this actually speaks to a point about the spec, which is: if you're planning on a faster kill, why wouldn't Rapid Recoup lose value, as you stated, the reason Hunters go OOM is because of Volley spamming in P2? If the goal is to get through these phases faster, then you logically should use less mana overall, so my question is why would you not put the TSA point into Improved Barrage for more damage instead of RR? If you guys had everyone alive and pushed P2 one valk wave faster, you actually wouldn't have third set of CDs in second transition. They would be coming off CD in first room. You would be almost guaranteed to have to dip into Viper for more than a Steady to get through second transition since you don't have the crutch of the 40% max mana from RR. You also still wouldn't have enough DPS to push one room, so you're still playing second room and losing a round of CDs, unless you are planning to use CDs outside of lust/execute, which further diminishes the value of RR by a great deal, as the only time it's actually valuable is after first transition and in second transition, since you would go straight into first room with the last time you used CDs being the beginning of P2. So you would be giving up 2% crit on Steady and 4% crit on AiS/MS for mana recovery at one point in a fight where mana isn't actually an issue because of Aspect Dancing. Ironically, if you were planning on playing 3 valk waves, then you could probably just get by Aspect Dancing in P2 to get you through to P3 without ever actually casting a single Steady in Viper.
Admittedly I don't usually change my spec away from the standard do-everything Trap or normal 7/57/7 spec unless I'm participating in a speed kill or something special, so I will be sure to try the 2/2 RR spec after the Christmas break as I never would usually consider putting any points into RR, since MM has the highest crit modifier in this expansion and an extra 4% crit on MS/AiS is juicy, and managing mana without RR is completely fine.
I would come play on Icecrown but I don't have a geared toon there unfort :)
