I don’t think it’s out of the ordinary for someone who plays a pvp game to mostly just play the mode they like. For example I only enjoy playing 1v1 when playing Smash Bros, it’s a very different game to me than when four players are doing a free for all. And as someone only recently trying FFXIV PVP I’m enjoying CC but not Frontline, and haven’t tried Rival Wings yet.

But what’s your real complaint? Are you needing to wait a long time to get matches for the mode you want to play? In my case I’ve mainly been playing casual CC matches on Aether but am getting matches quickly despite playing late at night.
