How about save/load codes?
Many warcraft 3 orpgs use the system.
A remarkably good orpg that managed to utilize this system and stay good was dark invasion 2. (http://www.thehelper.net/forums/showthread.php?t=91786)
You can fix camera lag.
I've seen camera render distances being modified in the following maps.
Peredition, Mars Sara.
You can look into the triggers for more info.
make the target box larger to compensate for high lat.
Cameara Jolting? Someone's going to come up with a solution in no time.
It's probably in the animation.
if you must give up, can you release your stuff so that others can make progress?
It looks pretty damm impressive. Without jass eh?
