In Mass Effect 3 I chose Infiltrator for the ability to snipe and Cloak, but so far I've found that I run out of Sinper Rifle ammo fairly quickly and Cloak doesn't seem to help that much aside from the damage boost.

How can I play this class effectively and what skills should I focus on? The melee damage boost skill seems useless (except for the increased health) since even with cloak running in and bashing on enemies doesn't seem conducive to living, nor does it pair well with sniping.
