Limit the number of ladder available character

In Korean stream, AfreecaTV, the streamer’s level is seperated by 14 tiers, because current ladder system can’t not represent their level properly.

When we play ladder, we can meet plenty of barcodes and placement characters. Do you really think the placements are the real new players? I’m sure that they are all smurfs.

When you see the Top ladder board. There are plenty of hackers and pro streamers who have several characters with same account ID.

Blizzard, Why are you allowing this? To make the ladder system more useful and effective, you should limit the number of ladder available character and ban the hackers.
