@badnetmask @ch1m3r4c0mpl3x I think the missing piece is like, if you didn't get involved in Plague Star, there is a pretty significant penalty to that, in that you don't get to get the rewards until they rerun the event. There's also stuff like Orphix Venom which had me playing nonstop for a few days in a row just to grind, or the Acolyte's Return thing, where I grinded for ages for a Maiming Strike...

It happens in warframe, it's not that common and it's usually fine about it to me.
