GW2 has lockboxes. People end up with something like 130 Black Lion Chestts to 3-4 Black Lion Keys, which are conveniently purchasable on the Trading Post (double clicking the chest will send you to the store).
Apparently that is sancioned and OK in GW2, LoTRO, etc and not for this game when it goes freemium. The hypocrisy of double standards in the forum by some (not all, some) is still amazing.
Nobody forces anyone to purchase keys. Heck in LoTRO, I sold the boxes as I am simply not into gambling in an MMO. It's not why I am playing an MMO.
Besides, it's a non-issue as there is zero evidence that anything in a lock box cannot also be obtained in game via drops, GTN, etc.
