when i play all is getting well, but sometimes the game encounter an error out of nowhere and this happens after the patch 2.6. i really think your patch notes is bugged or instable ; i got the number of the error AF66EDB5-E9BD-4BAB-B726-1F51815E1DC2
A progress rift will be nice too, like more far you go in the rift, more difficulty you get and drop chance up and up, maybe the rift gardien only spawn at your first death. So probably that will be a real challenge VS the death. And i think a different way to get these keys will be good too. And for sure some items or spell is totaly useless i hope Blizzard make new things or build for that. Because LoN not work well for all items.
