Newbs to QL probably play FFA/CA or CTF for an hour or so and get beaten easily, spawn/die etc and this presumably makes them think its rubbish. They might even get booted from a server for unbalancing the teams!! Not good!
So if I were incharge I would make Freeze Tag & Insta Freeze a free mode and try to push the newbs into playing that. The 'veterans' would likely stay away from FT as they would prefer playing their usual modes but more importantly in freeze tag you don't actually die, you just freeze until thawed out. Players can unfreeze their team mates for points to make up for poor skills (which will get better!) and you are in a team by default & helping out teamm8s. I think this will get newbs hooked onto the game better than spawn/die/spawn/die/quit - Ideally the newb servers are 16 players so the poor newbie can go about his business without unbalancing the teams.
So, relaunch QL and push Freeze Tag as the default mode or starting mode for newbs. I see no benefit to QL whatsoever by keeping FT a premium only gametype. There is even a community of FT players stuck on Q3 that I am sure would move over to QL if FT is free. Its the newbie gametype ql needs. Sort it out fs.
