1: Regen Master: by the end of that game I had 50 stacks which equated to around 90 hp/sec of regen.
4: Clockwork Steamfists: You can also use RRR but for Shrines in particular since I was wailing on objectives constantly, I felt that was a superior choice.
7: Gunk: Defense -and- Offense. A deadly combination.
10: Robo-Gob: The ability to manually target your turrets on a specific target no longer makes Grav the clear no-brainer pick. Against that melee heavy team, it is the almighty zoning tool.
13: Turret Storage: Moar turrets. Sprint is also a good pick if you are on your lonesome a good deal of the time, like Dragon Shire
16: Superior Schematics: Extra turret damage does not hurt, and since you didn't put any points in Laser or Xplodium, kind of a nobrainer since you'll tend to stick near your turrets anyways.
20: Mecha-Lord: Chunking Illidan and Zeratul while standing my ground is a hilarious sight to behold.
