1. Doable. Blizzard is showing to be open to changes that are "difficult." This would increase appeal to casuals and competitives alike. It would help the game succeed.
2. Smurfing already happens. Opening this would change nothing. At any point, I could tank my single account's ranking down by dropping matches, torture Bronze or Silver League for as long as I please, then rank up at my pleasure. Your second concern is irrelevant, in my opinion.
3. It would require three separate MMRs. Four if you include random. That's it. The leveling system is designed to award more points to people who play all three races, but this shouldn't come at the expense of having too weak opponents for your main race or too strong opponents for you offraces.
This change, I strongly believe, is a MUST for Starcraft II to succeed on as grand a scale as I know we all desire.
1. Fair enough.
2. Fair enough.
3. Totally not the point. I'm not talking about the leveling system, I'm talking about Ranks. I.E. I'm rank 15 Diamond.
If you separate MMRs, then I could play up to my current MMR with Terran, gaining X amount of points. I could then play up to my current MMR with Protoss (playing weak opponents and winning a TON), gaining X amount of points. I then could play up to my current MMR with Zerg, gaining another X amount of points.
At the end of the day, I'd have 3X amount of points, therefore throwing me into a nearly unsurpassed point value within my league.
I understand that people don't care about rank a lot, but some people do. People who play one race will immediately no longer be able to compete with people who play three races.
So I could be forced into Rank 100 Diamond, but still be slaughtering Rank 1 Diamonds, or even Rank 1 Masters. The entire league ranking system would lose it's meaning.
Riddle me that, Doncroft.
