It's probably not the exact version, but most of them are pretty similar. http://swtor.askmrrobot.com/skills/sage#0-2120322122122020303-1001312030203

I'd go Concealment until you are 30 as it's the only tree that gets a good ability to burn your TAs on before that. Once you hit 30, you can try respecing into the two other trees and see if they fit your play style better. As for a build, I'd recommend this one up to 29: http://www.torhead.com/skill-calc#401MZGbzrdbz.3

I'm not sure if you're still looking, but a 23/23/0 Hybrid is an okay mix of healing and dps for soloing. Here is what one of my Operatives is running at the moment. Don't expect to top any charts, but you will be pretty hard to take down. For instance, Sever Tendon + Pin Down makes breaking line-of-sight to get off a Kolto Injection + Surgical Probe heal pretty easy. You also have access to Lacerate and a good source of TAs for chaining the Collateral Strike stun mitigating a lot of damage from the weak/standard mobs. As for flashpoints, I haven't taken the build into any hard-mode 55 flashpoints as the main healer so I can't really vouch for how good it would perform in that regard, but I haven't had any issues with the other flashpoints.

I found Concealment to be the most enjoyable and I preferred it over lethality for more bursty dps and a few of the utility skills for leveling. However, I normally put two points into Incisive Action before climbing the Concealment tree. The shorter cooldown for Kolto Injection and the ability to make sure I go into a fight with two charges of Tactical Advantage for Lacerate is hard to pass up.

I'd like it if the Concealment tree was given a skill that added a full cleanse to Cloaking Screen, maybe to Advanced Cloaking. I've always hated having to burn Evasion just to cleanse a DoT.

Can a player still get multiple Tracer Missile stacks from seperate Mercs (5 from one merc and 5 from another)? Curious if maybe more than one player was involved in debuffing the OP.

If only the consumables weren't so expensive. Netting <10 comms a match can really drag out the grind.

Cover is handy for Explosive Probe and Kolto Injection. Cover is good for Injection because you can't get Force Leaped so you have a higher chance of getting the cast off without an interruption. I have no experience with it personally, but I've been told that Take Cover can be an effective way to roll through the hazards in Huttball.

It's a checkbox in the Interface Editor when you select the Operation Window.

I'm using a hybrid build and I run with Temple because then I always have the option of running around kiting/healing while she picks off the mobs when I get in over my head. Ranged companions are also less likely to stand in the PBAoE fire patches and die because of their half-dead AI.

A few new maps would be welcomed.

Tactical Opportunity shouldn't be necessary if you're using Kolto Probe properly. You should never be short on TAs.

What's the point of picking up Energy Screen and Flanking? Cloaking Screen's heal debuff has been fixed in 1.2 and I've yet to burn through my energy fast enough to make the two necessary. I actually think something like this 25/14/2 might be a bit stronger.

Update 1.2's Patch Notes are up on the PTS forum. Kind of bummed DS wasn't made into an instant cast HoT. Would of been a nice answer to the Sorc's bubble.

You're forgetting Meticulously Kept Blades' 30% surge bonus.
