Fed can't dominate clay tourneys, even since his first year; he couldn't dominate hardcourts the last 4 years against Nadal either. He needed luck to beat Nadal & Djoker on clay (the reason for winning was not that Fed's draws were difficult because no one except Nadal & Djoker won big clay tourneys consistently).
Losing Masters titles in a 20 month period & reaching finals with easy year-long schedules didn't count as "domination". Sorry to burst Fedcrier's bubble.
Again off meds, spreading trash in public? sad.
