After game #2 i'm still really unsure how to build Naut. His shield really doesn't scale all that well (10% doesn't amount to much) I had around 1k bonus HP last game and was only getting 100 extra on my shield which meant it was only absorbing 380 damage, not a lot on a tank, especially when I could play Blitz and get one that acts almost like a second HP bar.
I'd rather his Q didn't interact with terrain, it's more annoying than anything else atm.
I still feel like his ult is on too long a CD to make him a competitive tank, although when you do get to use it, it can be pretty sweet.
Anyway, on to the next game.
