Basically it's all about bringing the situation to the same place it had been earlier. The points you have mentioned are logical and correct . So, it's better to EITHER make it gold purchase for non tradeable items and plats for tradeable items , OR make the token items ( non tradeable) just as worthy as the Platinum items ( tradeable) rather than nerfing it to prove platinum spending people are much needed in DL .
Even we have spent platinum to buy things but now things seem different as if it's not the same as earlier and affects the newbie to a certain extent who don't know what and how it used to be before.
And now we see that everything's coming back as a vendor sale to a certain extent so I don't have any idea regarding the economy of the old items which seemed to be precious at a certain time . Things have changed so it's a good opportunity for the newbies no offense .
Hoping Cinco to see to the mild situation
