Don't be mistaken. I want a premade automatch system. And to be frank, the more skilled players generally do automatches in online games. Its just too convoluted to make a system where is separates premades and non premades.
You bought the wrong game if you're looking for a single player type approach here. Again, this game is clearly aimed as a team game. It needs to stay that way.
Well, you are making a repeated mistake in logic if you keep on asserting that people who want seperate AT and RT ladders want a "single player" game.
Single player games, by definition, are played alone.
Even a 1v1 match, is not single player because there are in fact, 2 player playing the game. But then again, I don't see anyone here even arguing for 1v1 matches.
I like pantheon matches where there are at least a few people on each side. It makes a more complicated and nuanced game.
What people are saying is what we have now is essentially a "random teams" format and they want to preserve that.
Others want an "arranged teams" format. That is a perfectly reasonable request and should be a high priority goal.
The problem is that arranged teams SPOIL the experience of anyone not on an arranged team who is forced to face them or be on the same ladder with them. This has been the case of every game I've ever played from mmo's to rts's to shooters.
A simple solution is having seperate AT and RT ladders. That's exactly what good competitive game companies offer.
The refrain to this amounts to "that's not practical, there won't be enough people to sustain an arrange team ladder". Well, then that undercuts your argument that it's such a popular playstyle. If it was that popular, and I think it is, it should be able to SUPPORT ITSELF.

A reasonable compromise would be to have one ladder but only match up premades vs. premades. I guarantee if SD allows premades to face off against randoms in any ladder environment, there will be a huge backlash. I've seen it first hand over and over again in other games. It gets ugly.
