First off, thanks for the detailed feedback, its greatly appreciated over here at SoStronk HQ when our users decide to make the effort to give said feedback. Good feedback also deserves a detailed response.
On the topic of transitioning from old school DOT R PUG's to MM PUG's. Instead of going back to the old system which has its own disadvantages the biggest of which being that there is no skill based match-making - a core characteristic that is essential for proper PUG based play.
Also, its in our plans to further evolve the MM PUG system to be much more feature complete and also add multiple reward mechanisms with regards to Badges, XP, Karma/Rep, Verified, FPL-Like system etc on top which can only be done on top of an MM system and not a completely user controlled environment like the old PUG System.
I can write an essay on the multitude of reasons that we cant build those features on top of DOT R but instead I will just give the key reason. Any environment that is completely user controlled = potential for match fixing and user collusion which inherently makes any further reward mechanisms not applicable (hence points were never applied to the old system as well)
What we can do instead, is take your valuable feedback and improve the MM system during the beta, starting with:-
1 - Minimal cooldowns for griefers who do not accept at 9/10
2 - Cooldowns for the last person not joining and the PUG being made nonapplicable.
3 - Ringer system to enable people to enter 9/10 games whether they are live or just created so to fill up that spot.
4 - Fixing the 5 man disconnect exploit that people are doing to avoid cooldown & IR punishments.
Some of these are already being worked on. I hope this eases your mind with regards to where the MM system is heading and why its the correct way forward.
