Yes, all things considered I think the SPWW2 system makes for more dynamic battles. The firefights that erupt back and forth due to Op-fire realy enhance the game IMO. Having total control over every shot also really slows the game down IMO.
If a priority system is put in place and works well, I think SPWW2 will be far superior. And it looks like some sort of attempt at it is coming in the next patch for SPMBT and eventually to be added to SPWW2.
