I've never been a huge fan of conquest as many players seem to feel the same way. I find little motivation to progress beyond a certain point as I feel the rewards arent worth the trouble. Largely the conquest only toons that are almost impossible to farm for since the event doesn't last long enough or occur enough to acquire enough currency to buy their shards or when you have to purchase the pass to access them only for them to then be removed and placed into a random event that is even harder to beat. This happened with malgus where I got him to almost the halfway point only for him to be taken out of rotation and placed into those conquest events that happen at random and no matter how hard I try to beat them I always lose even with my strongest teams. It's so frustrating when something cool is released only to become conquest accessible because it will only last for a short time in the shop before being removed.
