Crystals - add a star to most dropsStones - eliminate 4-star, double 5-star payouts, and add 6-star. Catalysts- everything jumps up one rarity. T4cc -> t2a -> t5b -> t5ccThrow selectors or nexus crystals as rare big prizes, the way AGs were before.
My guess is t6b, t3a, full t5cc catalysts and champion selectors. Nothing less. Nothing more.
