I think Season 2 started as too generous regarding loots. So when a 0.5 patch came in, you felt it as useless becoz the gear you are wearing from when Season 2 started is way higher in ilevel than anything on 0.5 patch.
The only advantage i could see on 0.5 patch is if you are gearing up Alts.
I did the Nightfall Event yesterday. It was fine. If it doesnt work today, so what? It would be fixed right away. Too many crybabies.
