With this build, I'd suggest using your smoke granades a bit more aggressively - since a great deal of defence is already granted by your ult, throwing a granade on a ranged spawn may incapacitate said spawn for the time necessary for you and your team mates to get in melee range with them.
Do consider though that with this build you won't have any way of recharging your ammo or granades automatically on your own, so resource management is a must.
