'I love this kind of useless threads', says someone who's apparently accusing me of being 'rude'. Do you do irony as well as 'u' do spelling/grammar, chief?
I can tell I've hit a nerve with this topic. That's a good thing, IMO. It's the essence of productive debate. But no one has yet provided a case for keeping saves during combat. What I've said - for those in want of a synopsis - is that it's the temptation that's the problem. Saying you never save during combat is not the point. We're all individual, so your sense of restraint is not the same as someone else's.
If you want your saves during combat, cool. I, however, don't want them. And I think the option to disable them is the best compromise to the issue. Yes/no checkbox at the start of the game, and we're done.
