First off, I am an Operative Healer with decent endgame gear (4/5 columni and some Tionese / Champion for missing pieces). This post is an honest attempt to find out how Operatives perform over 1 minute while healing a single target and remaining energy/resource neutral. I realize entirely that some classes may be able to burst with higher ease, have more "Oh ****" CD's, or offer higher degrees of utility; that's another post (this one is all about healing numbers). I know that Mercs are often perceived to be the best single target healers, so I would appreciate any replies that post numbers in a similar fashion for comparison sake.
*Skip the following paragraph if you trust my rotation, or don't care about it*
My rotation starts with a double cast of Kolto Probe (our HoT), and within each 18 s interval of this HoT I am able to cast 3 Kolto Injections which can each be followed by a Surgical Probe (SP). In addition, during that 18 seconds I can always cast 1 extra GCD spell with time to spare in order to be ready to refresh our HoT, which usually means consuming 1 of the TA I generated from the HoT. In the first HoT period I use that time for a Stim boost, but in the next HoT interval I will cast SP since the Stim Boost remains active. Since the HoT is usually refreshed at around 16 - 17 s duraction, I am usually refreshing the 4th HoT around 50 seconds. This means in the last interval I only get 2 ticks of the HoT, 1 KI, and 2 SP.
So during the 1 min, I was able to cast 10 KI's, 12 SP's, 3.5 HoT's, and 2 Stims in total while never dropping below the critical resource level that lowers regen (60 for ops) and without using any major CD's like Adrenaline Probe. For those familiar with statistics, I simply found the Expected (Healing) Value of each of the abilities. For those not so familiar, all I did was find the average heal given that I didnt crit and multiplied by .62 (the chance of me not criting), and add this value to the average heal given that I did crit multiplied by .38 (crit chance) making sure to include the appropriate crit multiplier that includes bonuses from my medic tree.
Expected Heal of each ability can be found below:
KI - 3494 , SP - 1841 , HoT - 1743
So by multiplying the expected heal by the # of those abilities that I can cast in one minute, I can find the expected healing that I can do during 1 minute using the above rotation on my character. 10 KI totalled 34,941 + 12 SP totaled 22,095 + 3.5 HoT totaled 6102 = TOTAL HEALING 63,138 / 1 min interval while remaining energy neutral.
I apologize for making this such a long post, but I think it helps to give others an idea of how I came to my conclusions. I certainly welcome any comments or criticism of my numbers or methodology. Hopefully, we can get an idea of other classes output under similar conditions, although sorcs may be a bit apples to oranges
