Today, I tried hosting a tc_hydro lobby, and I got the "map type not allowed" message. ... ...
Even though it is the only official territorial control map, and somewhat confusing at first, Hydro is a very good, well built map. It is unique, fun, and as far as I can see, suitable for competitive play. If players would take the time to learn how TC works, they would enjoy it very much. Hydro is a beautiful map which deserves to be played. Furthermore, to quote the TF2 Wiki, "Hydro is ... one of the six initial maps included with the game's release."
Why, oh why, is the TC map type not allowed, while maps like "koth_wubwubwub", and "pl_badwater_rainy" are allowed? I, for one, would very much like to see Hydro played as much as the other official maps. It is a shame that such a map is so shunned, and disallowing it from being played on such a popular website as TF2Center only adds to the problem.
Please consider removing the restriction from territorial control maps. Who knows; perhaps if the TF2Center community starts playing Hydro, the community at large will also play it.
Thank you.
