Mitigation Sucks - Nobody understands it - No Cash

I main Brig in stadium and I play a AP and Rally Spam built. If we struggle with sustain, i get Aura Farming, which gives overhealth on inspire at 5% of my max health. this is great, since it reduces the enemies ult gain, and is basically a free health since i have inspire active most of the time. Drawback is that I don't get points for mitigation and pretty much always get way less healing since much of what would have been healed is instead mitigated before, so I get less points for healing.

But many just don't understand and flame me in the chat. They see I have high mitigation and low healing and think I just tank damage on my shield, even if i carry the round with damage, healing, kills and everything, if they died more often than me, they flame me.

Just now I had a round with 17k mitigation, but only 4k heal (the round before without aura farming I had 13k heals) and they were flaming me to heal more. This really makes me want to not pick it anymore, despite it being the single best item for the team.

If i go for healing instead, everyone is nice, but somehow everyone feels offended if I go with the best choice. Btw this happens at Legend.
