1st off, modifiers are not removed. A bunch still came into play, most common are wound modifiers. As said above, they seem to replace some tables/modifiers. The physical exchange of tokens and the ability to modify pools with them is much more fun for the players. That is the point of playing a game. This gives a sense of reward.
2nd, Shadowrun isn't a simulation, that would be boring, just gives the illusion of one to create realism and depth. The new edge system just makes it more fast pace and fun.
3rd Don't judge it till you play it, period. I understand that this kind of debate is what online forums are for. I don't usually join forums for this reason. I have an ex-wife that's enough negativity for me. Unfortunately folks will look at the negativity and prejudge the game, that would be a mistake. I have played all editions, from what I have seen, the box set, it points toward the best edition since third. Not hot on the art, but that might be the Grognard coming out in me.
