The issue mainly effects users who are using low ppi display. MS cancelled the Cleartype on Modern UI and IE 10 because it works only on one direction --- which is useless for tablets. When your PPI is high(most new tablets has high ppi), it doesn't matter. The text is still sharp and clear. But for minions of normal laptop users, the blur is unbearable, especially for east-asian language users.
The solutions is quite simple: make cleartype as an option in Modern UI.
