Not only bad matchmaking (gold 2 vs diamond 2), vs player with 5 natural diamonds (i have also 5 but just levelled for skill points and with any node unlocked since they're Stand Out and Furry Fury), 10 gold turned diamond (i have 5, the other was a bronze), but also impossible catalyst against mine, I don't think the system check the catalysts of both players when crate a rift match. And also I don't think the devs tried all the combinations of catalysts with every fighters.
Just an exemple of impossible rift: boss node with a level 60 diamond Resonant Evil with those catalysts on:
1) Darknut: start the match with 5 armor on, one stack of armor is removed after a 10 hits combo. Plus 15% of chances to inflict bleed for 15 seconds while benefitting from armor.
2) Curse of knowledge: 50% to inflict curse for 10 second when gaining a buff.
3) Futile resistance: opponents suffer death mark for 10 seconds AND take 6% damage when landing a hit that deals less than 1% of Big Band max hp.
Surgeon General as a support...
Tried Silent Kill, Firefly (bluer tresher), Filia (drill tempered) and Eliza (chaos banish) to remove the armor, nothing of these works. The only way to try to beat him is to inflict doom with Xenomorph, but it takes too much time, or try to tag him out, but when I put on a tag out move the enemy turtles a lot more. Plus there are other two enemy and Valentine can still revive him.
