As like always ucool schemes like silver chest in other words.Red gears from crusade are automatically vanished or turned too low at drop rate like it happened with silver chest orange gears in start drop rate was ok but now it gives nothing at all.same goes for red gears in start they where ok like one drop in 10 or more days what happened now ?? And on other hand crusade is again turn into child play one team enough to clear all stages please change red drop rate and introduce new difficulty.
