My own BA srms have only killed me once in the last two months. I think this is because every time I fire them I am in the air. Also, I think I am just very lucky. For jumping, if you dont want to use any of that precious jumpjet fuel, you can instead map another key to the BA jump that doesnt use the jumpjets:
To map an additional jump button for BA that doesn't use the jump jets find your actionmaps.xml file typically found "C:\Users\USERNAME\Documents\My Games\Crysis Wars\Profiles\PROFILENAME\actionmaps.xml". Right click on the file and click edit. Hit ctrl+F and find “jump” (Not jumpjets, mind you). You will see under the jump entry a “<key name="space"/>” and another entry just below that, change that second one from whatever it is to <key name="lalt"/>
Watch out, every time you change your actionmapper you will have to go back in and change this. To make this easy I have a shortcut to the file next to all of my other MWLL icons.
