I think the most annoying part of playing support is the "need healing" voice command. It is pretty redundant imo as you already see their critical icon. Like anyone is just ignoring the health bars and waiting to be asked.
Where is the "protect your healer" or "stfu and kill shit" or "you heal and I will kill" option. I really like playing Lucio and Zenyatta, but they are only as good as the people playing damage classes. Nothing more irritating than getting stomped and having folks folks spam that shit. You need heals that bad switch to support or play someone that can heal themselves.
