I understand a few threads may have already been made, but I'd like to throw some suggestions around that could help the server out. This post is simply my suggestive view on what could be seen as "good" changes. I am in no way telling what would work, but simply throwing ideas at a wall. Please feel free to add, or suggest your own ideas - or criticize what you see here.
Some from of contracts could spice up game play quite a bit - would love to see some uniqueness to the flow of the game as everyone literally bolts for shotguns, so maybe giving players the incentive to grab a different gun for a sweet reward could achieve this.
A level up system would be really cool, as progression + rewards are really a solid way to keep people coming back. Making the rewards for achievements enticing would possibly promote players to have something to work to.
Maybe some form of rank system (diamond, gold, etc...) would also be nice to see, as it's just another reason for players to keep coming back to the server. It also promotes a form of competition among the community.
Take a credit away from traitors OR increase the credit cost of one hit kill weapons (knife, golden sword, etc...) to 2. Traitors shouldn't be able to simply instantly have access to some of the most powerful weapons in the mode. Most T's will buy the knife (or others stated above) instantly, granting a free kill and requiring no skill.
Give more incentive to detectives to actually do their jobs - Most people don't like to play detective, which is understandable as your'e a major target and most likely the first to die from T's, so why not give detectives some form of reward for killing/iding T's? Maybe a small amount of points could work, however I am open to any suggestion.
Decrease shotgun spawn rate(?) I am sure this is possible, but I have no idea. Shotguns are very strong, and require little to no skill. I can see this being divisive so I won't argue this suggestion, but it is frustrating getting one shotted and not being able to fight back.
Show that a T and Detective has armor equipped. The more information given to the player, the better.
Again, this is simply my list of ideas that could positively impact the server - it is open to suggestion, criticism, and any amendments by me.
