Good question but I dont think it would ever happen. WhiteFlash has a mappers Discord and everyone can be contacted on there. Relic could have several maps picked and ready in days. Every mapper dreams of having a map in game, so I am 100% sure everyone would say yes immediately.
Currently most maps are small modes however, not the 4v4 maps that are really needed.
Could be a great situation for everyone.
- Build support for the community. Everyone would be excited about it. Would show good will.
- Get fresh content quick.
- If the maps are not great, it does not show badly on Relic since they did not make them.
In the past Relic has taken 4-8 weeks to put maps into a package and get it out. Again... it is Relic we are talking about... so.....
Add a shit load of community maps. Add some vetoes. of course there will be some duds but even they would provide some much needed variety.
We do desperately need some 4v4 maps (and all the other modes ofc).
