Okay, for one, your attitude is pretty terrible. Two, consider using the edit button instead of posting four top-level comments on your own thread. It makes you sound desperate.
Now to deal with your complaints.
1.) Comes down to luck of the draw, I think. How much "lower skilled" are we talking here?
2.) I believe that "blocking" someone consists only of a mute, yes? Are they still muted? If not, this may be a bug.
3.) I don't believe we have a direct answer on this one, but the logical response is "yes." If you can't beat opponents who are better than the people you "should" be playing in your current division, you shouldn't be moving to a higher one.
You may be one of the many jerks who continue to make this gaming community continue to decline. Your opinions of me were not asked for nor informative.
1.) When there is a "matchmaking system in place that is intended to promote fair gameplay," matchmaking should not be "luck of the draw" as you say. It should be just and accurate based on skill, not on a MMR that is too dependent on others.
2.) Blocking SHOULD be applied to matchmaking for obvious reasons.
3.) You fail to realize this is a team game. Regardless of my play, I have no control over other players. To ignore the fact that feeders can greatly decrease anyone's (including you) chances of winning is not only naive, but arrogant. You aren't even level 30, so I doubt you would understand. Don't reply back with this is my smurf account either, which is another issue within League in itself.
