[Rant] This game's practically dead in terms of actual content.

Progression tied to drops, pay functionality used for cosmetics and convenience, trading top tier "mods"(not sure what that is but sure sounds like the karma scissor system)... I mean it sounds like how MapleStory used to be before they fucked pomegranate up.

weapons are craftable by the players, you have the option to buy weapons straight from the parent company with cash shop currency or farm the materials to make it
farming the materials to make damn near anything takes less than a few hours.

mods are what get slotted in to the weapons in order to strengthen them. different builds consist of different element / power / utility combos.
