Sure people are against it. Seto Here in this post is against it. Plenty of people have spoken up in random forum posts on this topic going back as far as the beta or even alpha.
That’s totally fine not liking the idea, but I just don’t get the rationale. The argument always seems to be people worrying about trolling games with monster-hunter team’s that don’t really fight each other and just screw around, and people abusing the leaderboards or masteries.
Masteries can be farmed in custom, teams can screw around in custom, and the leaderboards really affect no one. I’m really looking forward to ranked matchmaking so they can feel better about opening up skirmish matchmaking for group monster play.
Sad part is, unless this change is already done and in the second title update, we can’t expect to see new matchmaking modes, game modes, maps, or anything of significant change for another 2 months.
I suppose it’ll just be bundled together with the next DLC release.
