You know that was just a coincidence right? Every person i have ever talked too said their magura brakes were incredible (including me) you probably messed something up in the brake when you were bleeding (and don't tell me that you work at a bike shop everyone makes mistakes) the first problem you probably had a manufacturing defect and that's what was wrong with the lever (Also the mt7 is worlds better than the mt5 it's made out of a carbon nylon mix instead of just nylon so it's quite a lot stronger and the levers are way better)
