I really respect your mod, buddy. Now, I play all the old, not so powerful levels, for quake, your mod, gives a chance to look at them, in a new way, to get acquainted with them. But I noticed that you removed the shotgun and left the machine gun for all the characters. Maybe you can make all the characters different weapons? 2-shotgun. 3- machingan, 4- lightchting gan (which is converted into rail gan, which works through and through, as in the first quake). And 3 versions of the one character. 1With armor 2With weapon 3empty. For a more radical difference, you can change the speed of the characters. 2-normal speed. 3-fast speed, but little health. 4-much health, but low speed.
But sad what mod havent got delay when weapon are changing.
