I can understand that a lot of players / pro players do not understand this idea, because after all we are there to play with the rules we were given, not to try to transgress them.
But the main argument of Blizzard for the 12 collectors was that it would energize the game, and make it more alive for the viewers. Since we have lost more than 60% of our viewers, most people do not raise the game again, the pro players games are no better than before. We have not won anything with this change, and now that everybody plays on 12, the community will always be divided to go back to 6, because many players give their opinion without ever taking the time to replay on 6 collectors, until recover the sensations of play, to judge the difference between the 2.
The best argument being: The game is too slow on 6 collectors. Which is wrong. Another argument is: The game is easier on 6 collectors, which is false, the game requires more mechanics but less precisions. On 6 collectors, a depot that must be placed at 21, can only be placed at 21, if you put it to 20, you'll have 2 less marines, if you put it at 23 you will be supply bock at 27.
So the game is no easier in 6 collectors, it is deeper, more precise, and low cost units are more important at the beginning.
I do not understand how the team that manages the balancing can not see it, the 12 collectors is a mistake, of course that going back to 6 will create a conflict with some players, but how many will come back? how many will understand over time that 6 collectors is much better than 12? It's sad, sad to see that the people who created the game do not question themselves. Blizzard will make all the changes of the world, if we stay in 12 collectors, no player will return on the game, no caster will make a tutorial, it shows, nobody plays on the server test, because the problem of the game is in its dynamics more than in its balancing.
