Alright, I feel obligated as a TMD veteran to share my two cents. Here I go (most of it is probably repeated, but oh well):
1) Walker bites/Antibiotics- Those things were the BOMB! It adds realism and a better rp experience, as said before. Also... they can help cure golden barrett shots.
2) Fix the bikes as soon as possible- Cars can be annoying, as they don't fit through the forests as nicely as bikes.
3) Better loot in the Portal 2 easter egg (If you don't know what I'm talking about, don't worry about it)
4) Figure out the problem with shotguns- people always say that the Double Barrel Shotgun does more damage/is better than the Spas 12. I personally have no idea why this is, I just think it's something that should be looked into
5) Do not bring the infinite money cap back- just my preference, I like being able to pvp more often since I'm not as focused on hoarding.
6) More competitions for TMD- this would allow for more social bonding with players and staff. Maybe offer some sweet prizes? Like a delicious muffin?
7) Remove the Mythical rank from crates or completely nerf it's chances of spawning- It seems like everyone on the server has this rank, now. And to be honest, it's pretty OP. I have the rank, so don't think this is biased for not having it.
No need to nerf, but just make sure you aren't having such an influx of Mythicals.
8) Walker Herds- bruh that'd be so damn cool. Also a good way to farm those walker kills for achievements and money.
9) I don't remember those 1 hit zombies, but if they're like you say..... no thank you. XD
10) Implement some sort of item selling feature, so you can sell the items. That'd be cool. Maybe not allow people with infinite money to do it?
Other Various Things:
-There's a random Jesus NPC out in one of the forests... What.
-Make tree camping harder (raise trees, etc.)
-Some sort of reward system sounds cool, for regular players
-BRING BACK THE MALLOW BRIDGE SAFEZONE (sorry, that place was like my childhood. I lived there during my noob days)
That's all I got for now. I'll come back if I can think of anything else. Love y'all!
