This built is only for those you like supporting their group. Your only job is to stay behind and keep healing and protect rest of group. Boring but trust me you will be like a drug for the group. They will always need you.
Playstyle is like:
1. Use support station after you see members take spots. Skill haste is not so great. If you create a wrong spot for support station you will regret it.
2. Keep an eye on players that need healing. If you see that someone going to die, let him die and then pop the heal that gives also revive.
3. Use Signature Skill asap and be always the guy that rezz others. Leave group do the dps and you will be responsible for the rezzes.
4. Use Sidearm to lower your CDs. Especially while Signture is not up.
5. Use Caduceus when you know that group will not gonna die but also want to burn enemies down fast. You will give them the heal that needs to keep them up a bit. Use Midas for bosses or mobs that you know that they will hurt your group.
