When they removed PTS from Grand Celestial upgrades, their philosophy was to alleviate RNG for the upgrade process.
Now, they're pulling this stupid crap by reintroducing RNG into the Heart upgrade process, which doesn't make any sense at all.
Also, PTS needs TS and RNG to craft. TS needs moonstones to craft. Moonstones are obtainable either by PvP or by swiping (I don't count PvE as it's not reliable). They're basically forcing the players into one of those 2 options. What do you think will happen when the new player finds out that he requires half a hundred PTS for a measly upgrade? He will quit, plain and simple.
I want to hear an official word from NCSoft on this matter, and I sure hope that those PTS numbers from the sheet are a typo.
