This is in large at fault for the overwhelming number of players critical of the new fatigue system.
Whereas the new fatigue rules are well sound, the means used to counteract the debilitating results are not sufficient.
by doubling or tripling the effective hold breath time, it could be possible to achieve a very elegant balance that favors tactical gameplay and realistic strategic compromises.
additionally: when firing from a deployed position, weapon sway should be always minimal (as if holding breath).
fatigue should not affect the stability of a deployed weapon, even without bipod. This is also a fact I have confirmed by personal experiments with a weight & shape analog sports air rifle (C.B.C. "Montenegro" Carbine + scope)
