On this I'm pretty much with aj0413, if it does not effect other players everyone should be able to save when he wish to. Limited saves should be for special ironman challenges like Honour Mode.
If people want to save scum everything, it their own loss.
I once accidently started the Deep-Dweller abush with my friend being deep inside the enemies and me being outside, still needing a way to catch up. I had not safed for long, so I saved at the start of the battle. First try of fight went downhill, so we reloaded with the same disadvantage position and this time we managed it. Would no have been possible with suspend saves. ^^
