Facing such situations is a nightmare for any fool who have decided to try out playing as OKW. The ISG is a joke now and the damage of offending units (Mxim, vickers) is so high and that approaching and using incnades is not rational, needless to say you don't have enough resources to spam incnades by that time and when you can approach the building it is protected by shockies or CMDos.
The sutka went under multiple ninja nerfs in terms of AOE and Scatter so reducing the cooldown won't hurt that much.
