This is very frustrating since it is difficult to remember to change the rate of fire EVERY time you spawn in. It can also be a bit jarring to have gun fire in a different mode when your expecting it to fire in semi-auto. I normally keep the Grendel in semi auto most all of the time, and have died numerous times because of it. This is standard behavior on most other shooters, and it'd be nice if this were implemented in Crysis 2.
