If I were Gravity, I wouldn't release it. Gravity cat's server is enjoyable because it is unique. You release these and you open pandora's box upon the server list. After thinking about it, I think that if this is release, it probably won't really be good at all. Anyone in this topic that's asked for the release is a complete moron. It will turn into T+T where the whole purpose of balance(tactics for this pack), becomes lost because everyone just spawns the guns in any old blockland save they have, and soon every server is running this, and it will get old fast. It doesn't lose its touch now because only Gravity Cat's server has it.
The only ones I would even think about releasing would be the ones that can add something cool and new, such as the stinger, the mines and grenades, the binoculars, the flaregun, and such. Releasing it all the rest just creates more toys that all the kids here will shove in their mouth.
But it would be wrong not to release it after showing everyone all of it, so release it anyway when it's time.
