A player can spend real money to purchase something that gives them an advantage in the game.
"Premium currencies can be used to easily obtain a maxed-out new battlesuit, its weapon, and its stigmata. All of these are required to stay relevant in the endgame competitive activities."
"Paid premium currency can be used to summon on special banners which can guarantee a rare character, usually from a pool of several. The paid subscription service also gives additional rewards, some which a feasibly unattainable in any meaningful amount as a f2p (light/shadow) points. However, none of this advantage is specifically locked to paying players (apart from maybe large amounts of light/shadow points)."
"The PVP aspect of the game is insignificant to the average player- so naturally the p2w aspect affects an very small amount of players. There is no p2w aspect in non-pvp content"
"Gems can be exchanged immediately for Held Items and Item Enhancers (used for upgrading items). However, most players obtain them through free introductory reward quests (especially three lv.30 upgrades) and do not fully upgrade them as the advantages are modest."
"you can buy both gold, used to buy better equipment, and bloodstones, used to upgrade them"
"Some mechs and weapons are sold for premium coins. You can also buy your way to better equipment"
