After a lot more playtime in the mode, I have some more opinions (yay).
First of all, the is the most pay to win thing CPG has ever done, which is very surprising. Not a huge fan of that, running into Zaowi's Cyclone Mask Adamantine Claws or that one Faie with Makantor and Regalia and Spiral can just feel unwinnable (I don't even wanna know what Dragall's running). It's not that bad, just unusual.
Secondly, the matchmaking is whack. Rumor has it that the matchmaking only takes into account who's queuing, and nothing else. Feeding me silver players makes it easy to hit the leaderboard, but it isn't fun for either party.
It's also matched me with the same person twice in a row on three separate equations, which was a bug in other gamemodes fixed a long time ago.
My final gripe is, of course, rewards. I have no problem with a lack of gauntlet-like rewards, but having no 3 win 15 gold or faction xp gain kinda sucks sometimes. You lose money by tipping, and I would love to use this mode to level and practice other factions.
