Do you mean put just 1 point in your first row of offensive skills then last tree max everything for full support?
I put enough points in my Medic to max out my stun. After that I maxed all my heals, eradicate, revive and healer’s blessing (I’m level 48). After that I maxed out my move speed and put 8 points into passive HP.
When combined with +10 shoes, my move speed is faster than any close other than the sentinel. It works out well when being attacked because then they can be kited until either I can kill them or help arrives.
Well, your DPS stinks so no real need for shots once you clear lvl 39. Better off keeping the minimum, maxing out your heals and your passive HP to make yourself tankier. One think about 49 cap that folks underestimate is crit-void. I had a medic on Aeria’s version with like somewhere between 7-10K crit-void. Took about 6 people to take me down due to it. As for the heals, make sure you have all your debuff removers and you’ll be good too. Knew I couldn’t beat her, but once sat there and removed the debuffs off myself, along with healing, so much that a higher level whipper gave up and left me alone.
I agree with the whole thing, but, what about the passive skills?
I’d put points into maxing out your passive HP once you have enough for all your heals. 30-35K HP on a properly built medic will make you one hell of a tank.
