One criticism that I have with most maps (CTF maps especially) is that there are not enough weapons to go around. On many maps (on a full server), I will spend 80% of my time shooting with the shotgun and looking for a weapon. If you are a map-designer, please consider adding more weapons to the map, not to mention health and armor also.
I guess what I'm suggesting is to design the map for a full server in mind (12-16 people).
Anyone else feel similarly?
