First up... I didn't think I would enjoy the invasion mode but actually had some fun doing that. I ended up on both ends of the shitty stick for that but hey ho... you win some & you lose some. However, the double cross 1V1 is a -blam!- fest of sweaty try hards and a hateful mode. Not fun for me. Opinions will vary. Seemed to get roughly 60/40 split on the modes. But if you're interested in the seal you will make progress either way. As for the crystal... took me around 35 games for it to drop... and it dropped from a 1v1 where I was being farmed by some trials puke. So I guess I'm trying to say stick with it... it will come eventually. So happy days. I never have to play that mode again😁
