It's because it is impossible to point the tier with no breaks as single one with the code we are using to create a tier as it would stretch the page, and the MediaWiki scripted code will render he half unviewable, they could be one but Void claims it is not a huge tier. Therefore, given the fact there are 21 characters in those break-less tiers, I sorted them in groups of seven for the mere sake of good accomodation.
Damn it Goku I explained this to you about how the tier positions should be set up. You need to stop being so damn impulsive and use your head more. You along with SSBBSonic and Cancan need to think more.
