Also as it is now combat or preperation for combat probably does take up 30 min of a 2 hour gaming session, I think it would be fair to say it take up more time than that. As it is now its just that many more encounters are faced.
Looking at the thread that spawned this off-shoot, its easy to see that combat is a huge problem in terms of game balance and representation of canon.
A localized pausing system isn't the solution either, because its up to DM implementation and we would need many more DM's for such a system to work.
For lack of a better example I'll use this one(i.e., a pack of orcs are unlikely to gut my PC, so I can probably manage a *swings overhand* "Yield, pigblood!" and be little the worse for wear).

Any time that a Pc is out numbered he should be worried, its about numbers after all. 5 orcs even if they are CR 1/2 or CR1 could pose a problem for a mid lvl fighter if he took them on alone. Now low Cr's pose little to no threat, factor in cleave or to be obscene great cleave, and a mid level fighter can wade through a city of gobo's. To combat this, either mobs Cr's have to be falsely inflated to make up for AI short comings, or mobs have to be reduced to near zero Xp for the fact that it is easy plow through them, this is also due to Ai IMO.
Both these solutions lead to PC arms races and kit builds, and all sorts of the things we just got through talking about.
Playing in this style would level such things out across all of ALFA but because it depends on DM's completely I don't see it as a viable option in a PW as large as ALFA. But such a thing is viable for people who wish to play in this style, or DM's who wish to run encounters that feature Inteligent mobs.
