Ogre is better than Yukon, at least on PC where Yukon is 50/50, you kill or you'll be killed (due to insane RoF and long reload).
Personally I'd grab Ogre, however that aim assist on consoles may benefit your Yukon experience.
Aren't you talking about "sales" which may appear 1 month (if not quicker) before game closing?
But seriously, 50%off should be a regular price AT ALL, Armas IS overpriced as it needs a change. If there will be 75-85%off oh dear, sadly I have most of Armas items I'd like to have so I'll pass anyway, I may consider if it'd affect also PS4 version IF it gets actually "fixed".
