I will start by proposing the existence of hard and hard tmq7 ud6 with mobs lvl65-69. An example would be that tmq7 had mobs and much stronger bosses to increase their difficulty with the chance to drop u65 and u70 reds and purple. All this because in the last update the purple and green stones are less likely to climb 2-3 points. Also many pjs spend hours usually 1 or 2 growing on papaya (I include myself) without getting a decent drop of legends or stones.
The same idea applies to UD6 because at this time BIDS lvl70 are not available in the game, making it difficult to get blue and green stones.
I know this is a difficult job for programmers, but I want to know your opinion on this.
