I think the most important thing for the new TMD pvp system is to keep it as realistic as possible. Pieces of bread should be the strongest melee weapons, doing 9.0 damage per hit. Juggernaut armor should be replaced with bubble wrap, and have the same properties as armor with feather falling 4. The strongest weapon should be Captain Miller's M1911, with a 1 out of 7 chance to summon a P-51 Mustang on hitting your opponent. Last of all, painkillers should be replaced with Flintstones gummy vitamins, and give jump boost 2 instead of regeneration.
Hope to see these changes implemented to give TMD a much more realistic theme, and make the game that much more enjoyable.
