but that's not how a spear works. If a person manages to stay up really close to you then you have a severe disadvantage. Spear combat is about one person closing the range and the other creating distance.

goblin: jumps past spear, attempts a strike
PC: blocks with shield, steps back while striking at goblin
repeat.

Besides, if it spears hit from a distance, then you start stepping back one square every time a monster gets near you, and that could be overpowered/cheesy. What happens when a monster wields a spear, you didn't think they could attack you from that range? Sorry, remember to always [l]ook at the monster you fight. I think you are confusing spear and pike, as the pike actually does act like this, except you aren't going to be moving very fast with a pike, so it would make sense to graphically represent this on the dungeon square.

The DV of the spear comes from its reach, the spearholder wanting to maintain the distance, and the swordsman, wanting to close in, but having trouble because a spearhead is constantly in his way. Once the gap is closed, its not a game-over situation.

Would possibly reduce enemy criticals since they won't take so many chances with two blades sticking in their faces.
I suppose that the result is divided by two before the critical bit is added on then, makes sense, especially as two-handed fighters have less DV to begin with.

A troll with two clubs sounds like the perfect group fighter now.
