I think nice features that all players could actually appreciate more than game items that wont even be used in matches could help the mod's popularity some.
/stats (yeah this could be hell making with all the weapons)
it obviously couldn't list all players like standard weapon q3 mods do, but individual stats for each class activated by a player would be nice. rounds fired/connected is a nice touch too. This isn't that important, I'd like the following more than this one. Maybe it could be added in later versions.
server top 10 records (score, cap times)
Auto demoing on matchmode. (STA)
Auto score board end map screenshots on matchmode. (STA)
Auto team balance (auto disabled match mode).
a spectator mode for recamming demos since q2 has a map(/demomap right?) record option. I donno the possiblity of this one, I just want it cuz I'm a video freak & want original scenes from a 3rd person stationary/ghost view taken from great match scenes.
I was going to say damage/alive time ratio but the more I thought about it I realized it'd encourage the DM llama crap many people hate so much.
