What manner of support are you after? If you feel that mapping is wasted effort and not enjoyable in its own right then i guess you probably shouldn't map.
At this current time (11:50am +10GMT) there are 10 servers with players on them. One has a user made map (fortress) with one player on it.
There would be on average one custom map for ever 10-15 default maps. It has been like this for the last 3 years. There are some awesome custom maps out there, yet no server hosts them. What is the point? When you have been mapping as long as I have (3 years) you will realise there is no point making maps as the maps stay in rotation for about 1-3 months before being completely phased out. Every default map (yes even fucking uncreation) gets more plays than the BEST custom ones.
No offense to the devs but Uncreation is the most unbalanced, ugly brown laggy piece of shit map ive ever seen. Yet it gets more plays than all 'fun maps' (otherworld, trempship, gauntlet, paint, even mission 1 has been phased out somewhat) normal maps (strangelove, sokolov, etc etc). Why? Shitty/no support.
Dont get me wrong, I love being creative. But with lightwave and UnrealED you can do far more. I would prefer people play the maps than make something that collects dust when finished.
inbe4 'cos your maps suck/unplayable'. Im talking about everyones maps, not just my own
