Might just be an isolated incident but I got a legendary drop from solo normal yesterday. I regularly get rare and epic gear from boss battles in advanced solo. Some challenges reward uncommon loot packs which have a chance at rare gear and then there is the coins you gain in pve 500-800 per map which can buy gear packs. If you are looking for specific gear you can check out some guides that offer which faction gives what gear.
Is it half a game because you aren’t getting what you feel you are owed on an admittedly low drop chance item? If so, you are at level 100 something that took me (again by no means the end all be all, just one guy) a little under 100 hours to accomplish. 100 hours in a game is usually considered a full game by Rpg standards and most RPGs run the same price.
Could you explain your position on this being half a game? I don’t see the correlation between drop chance and completeness of game. Though a number of times on this forum it has been pointed out to me that I might just be incompetent.
