If you make a map pack yourself and keep it for you, it's fine playing your own map pack.. However, once map packs for Elite - a scheme supposedly played on a random map - get spread, people are bound to run into hosts who put maps they already played.. Come on guys, don't get boring, don't be lazy.. Make your own maps ffs, HHC wrote a nice tutorial!
If you let this happen, there will be colour Elite maps with huge Chelsea FC banners on them soon.
