Indeed, should be increased. With a proximity sensor would be nice, or by having the secondary replace the primary again but allow detonating grenades with secondary fire as soon as they've hit the ground (although that's almost copying TF2's sticky bombs) :p
However that would allow one to replicate the functionality of the current primary by holding down both mouse buttons, but also have the secondaries more effective. They would then also need a more visible, glowing model so you could actually avoid them....

Gah! Don't do it, man! I think people are finally comfortable w/ mortar as you have it today.
