While i was around for the good part of tekkit, I'd like if possible to have the weapons mod from tekkit and used in the main server, just because it I think it would be personally more fun to play with, place cannons on your castle, have muskets to hunt, pvp etc. All the items required to build all these weapons are all basic components in minecraft so there is no ores or other mats needed from tekkit.
