Seems you're missing the fact that UM+EM combo is way better use of energy than useless KP, UM procs UH. I guess its a matter of play style. I use cool head typically on cool down. I can dump my energy in NM situations and pop CH then DS to get close to top and start spreading the hot love.
But yeah the "guides" have been done on sithwarrior with numbers crunched so I'm not so sure this is necessary, no offense.
