G502 middle mouse button 'double pressing'

I play a lot of DOTA and have looked around for a while now but still can't seem to find the right mouse that wont cause the middle mouse button to break after heavy usage. I love the feel of the G502 so its such a pity that its middle mouse button just seems to break so easily. I've heard the G903 is more suitable for esports but not really willing to shell out that much for a mouse. Currently using a replacement zowie EC2 which seems to be ok for now. But if anyone knows any mouse with a durable middle mouse button pls lemme know.
