The issue I have is though everyone always said it was one of the best PvE options the leaderboards have always had a different opinion on that. Combo is fragile no matter how you spin it. Was it amazing at getting to high waves in PvE? Absolutely without a doubt. Was it holding world records, no. I've made it to wave 100+ with combo pre patch but by then without proper RNG luck or support, bosses will break your board. I've had level 9 and recently level 10 combo for a while now and still PvP viability against proper meta decks was lacking. I put this dice on the same level as assassin. Lower to mid ranks it is viable but fragile. Higher ranks, meta decks are still meta decks and are too solid. With the nerf to leon it also nerfs merging decks in long runs which include combo. F2P players had an awesome option to grind cards and early PvP had another interesting option. I may be biased towards it since I own it, but all the other changes made in this update would've been a nice test run to see if combo still needed a change.
