Funny, season 3 ended today for me. Pet is underwhelming. Game performance just as bad back at launch with insane rubberbanding, which really doesn't work with the whole "Trap-theme" - at least not for me.
Season 3 ended for me once I did gauntlet a couple times. Blizz hyped that up and it failed miserably, the map designers need to do significantly better next season. They gotta rework boss mats too. Getting duriel mats is way too annoying right now. Lastly, fix echo of lilith.
