Bond of Stone's interaction with the Fearless mastery

Absorbing damage from your ally with Bond of Stone will activate the Fearless mastery. This isn't a bug per se because all damage (including true) activates Fearless, however with Bond of Stone it feels like they're made to cancel each other out. Playing tank supports, half of the damage you take while you aren't in a fight is from Bond of Stone. For example, if Caitlyn Q's my ADC I'm forced to absorb the damage and my Fearless will go on cooldown. This allows them to start a fight while it isn't available, since it can also make a big difference. Due to the pokey nature of bot lane, my Fearless mastery will be procced almost immediately whenever it is off cooldown. Bond of Stone isn't in a great place anyway, this is the least Riot could do to make it less punishing (if it didn't deactivate out of combat effects in general it would be better). The same case might apply for

TL;DR Bond of Stone procs Fearless, and with the constant harass of marksmen and ranged supports it makes the Fearless mastery rather useless.
