Traditional fantasy-based MMO classes redesigned for a post-apocalyptic setting: ( 8 / 9 ) paladins
The dedicated tanks and powerhouse meatshields. Paladins are pretty much the only class clad in proper armor (scavenged riot and police armor), unlike many other classes, where their armor is cobbled together from sporting equipment and other substitutes. As a result, they tend to be incredibly robust and are able to soak up huge amounts of damage.
On the other hand, the scarcity of shields forces paladins to scrounge up some pretty creative substitutes. Because true firearms are so rare, objects like car doors, thick metal sheeting, and steel doors can be fitted with makeshift harnesses and handles to serve as shields. While these shields would be easily punctured by bullets, they aren’t so easily overwhelmed by bladed weapons or makeshift guns, making them suitable for the setting.
Heavier two-handed shields can be used as weapons themselves, functioning like battering rams in order to damage foes; they tend to have higher defense, but their attacks are much slower and clumsier. Lighter shields only require one arm to use but don’t soak up as much damage; in exchange, they can be used in conjunction with polearms like spears to deftly fend off attackers.
