WildStar devs claim that they are listening to players' concerns over the infrequency of AMP upgrades and ability tier unlocks, which is why the team is planning to roll out several improvements to these drop rates in an upcoming patch.
"For the uninitiated, players earn AMP power points and ability tier unlocks naturally through leveling up in WildStar," the team posted. "Special items can be found throughout the game however that further boost your character's AMP points and ability tier unlocks. These items, based on our data and from feedback from players, simply do not drop enough."
Players will see a drop rate increase from level 50 creatures and PvP victory bags. On top of those, the team is putting in one-shot items from endgame reputation vendors, the prestige vendor, gold medal veteran dungeon rewards, and at path levels 15 and 30.
