"Just so we're all in agreement."
i find that funny as it's quite obviously not the case.
I understand OP's point (frustration?) and personally agree that custom matches are currently the only place for premade team to play.
what i don't get is why it falls to the rest of the community to alter their behaviour.
premade teams can only play in custom games DOES NOT EQUAL custom games are only for premade teams
you've been given numerous reasons above as to why people like to play in custom games (connectivity, specifying game type, etc)
you're also been given a reasonable suggestion of how the community can change so that everyone knows what they're getting into. you may not like it but the easiest thing is to say in the title 'premade'.
1. it's the first point of contact,
2.needs only be written once (the premades and the non-premades don't have to constantly ask/answer)
3. it all happens before connections are made. so there's no wasted time
this makes things toooo long!? i host using 'demidog - UK 3v3 welcome' that don't wash with me.
this is just my opinion, if it is an issue and you're asking for solutions. if you're not asking, then why should i?
<caveat> tbh, i didn't even know this was an issue. i play to play, take my chances and enjoy winning when i do and learning when i don't.</caveat>
