Don't get me wrong, I love 5CP. It is a great, complex, fun-to-play gamemode in this wonderful game we all play.
5CP is difficult in HL, even for the top teams, because so many classes have limited mobility. This means a slower paced game and more stalemates.
To alleviate this problem, the HL community, for the most part, avoids exceptionally large maps, because pushing off of player advantages is very difficult when they all spawn before your slower classes even get to the fight.
With that in mind, I'll congratulate you guys for including great maps like:
* Process,
*Gully,
* and (IMO) Granary,
but would really ask you to reconsider playing maps that don't cater to all 9 classes due to their layout, like:
* Badlands (pretty sure this was played in early UGC seasons... having to walk all the way up to Spire is not fun and the majority of classes have to do that),
* Warmfront (wipe at mid? Cool, you get 2nd and have to push into a last that people hate even in 6s),
* Croissant (this is played a lot in HL pugs for reasons I don't understand; despite being an overall pretty map, it's just too big and pushing off advantages is difficult for even the best teams. This leads to gameplay forgiving the worser team and drawing out matches that would usually be much quicker on a more compact map)
and more!
Perhaps consider using one of the gamemodes that is tried-and-true in HL, like Payload or King of The Hill!
