Basically, anyone who has been through more than a couple rollbacks understands the #1 rule about rollbacks- never, ever, under any cercumstances do them unless the game is literally at stake. there is a million things that can go wrong, items dissaperaing, units dessapearing, commanders becoming units, units commanders, orders not followed, gold/gems vanishing. I have personally, and many other vets as well, have seen games entirely ruined by rollbacks.

Now to be fair, every once in a while rollbacks go without a hitch, but generally people agree that its not worth the risk of ruining the game.
