Fastest Combat System for PbP?

[Another_Poet]

It's weird that nobody here or in any game I've played in has suggested this idea. When the combat starts everyone posts general actions and their general stats. For example a rogue might post Skevlar will typically try to keep in flanking trying to take down as many mooks as possible. Hitpoints x babx ac x + x vs etc. And then present rolls for saves or to hit and damage.

The dm would then extrapolate what happens each round and it's up the players to keep up (for example if the BBEG suddenly appears). It gives up something but speeds combat up by a decent clip.

I suspect people don't do it because the DM would be overloaded with work to do then. It's kind of a pain to make that many rolls for players. Some people might also be worried that players wouldn't feel they have enough control. That said I bet it would make things faster if the DM could keep up with it.
