I'm leveling as smuggler heals and have the following plan for my spec. I may switch it around for end game content and I am a former lover of pvp in WoW but not too worried about it as a healing spec yet.
Level:
10-11 Exploratory Surgery
12-14: Bedside Manner
Anatomy Lessons is a dps talent that I think may be a filler later on(?)
15-17: Healing Hand - This seemed the best of the second tier for raw throughput.
18-19: Keep Cool - restores 16 additional energy - figure this is like restoring mana?
Smuggled Tech reduces threat and pushback but I think this is filler. Scar tissue reduces all damage taken by 2%. Pfft!
20 - Slow-release medpac
21-22: Prognosis critical - Does diagnostic scan get better?
23-24: Sedatives Tranq looks like a nice CC and this can only buff it. However, I think you could fill in anatomy lessons or smuggled tech in here. Any comments?
25-27: Medpac mastery
28-29: Patient Studies
30 - Emergency Medpac Required for:
31 - Emergent Emergencies
32-33 - Homegrown pharmacologyX2
34 - Psych Meds: Triage removes debuffs.
35-37: Accomplished sawbones
38-39: Med Screen: I don't really know what defense screen is but I take it's something you put on tanks so I'm taking those points here.
40: Kolto Cloud: Big AOE heal
41-43: Scrapper tree: Survivor's Scars: Increases healing to 3%.
44-45: Smuggled Technology: reduces pushback by 70% and reduces threat by 10%. Headed back down the sawbones tree to pick this up now.
Last 5 points?
Could head up Scrapper tree to get Sneaky to increase movement speed and effective stealth. I was going to take 2 points in Browbeater to increase vital shot and flechette and then to sneaky X3.
Or fill in Scar Tissue for 2 points to reduce all damage taken by 4% and 2 in brow beater and 1 in sneaky. Shifty Eyed increases stealth detection and defense but not sure if that's very useful.
Anyway, I'm very new to the game (started last Saturday) and could use all the help available on this spec.
