The mercy was changed because it was difficult to properly intercept them. For this to be a problem with T2 bombers you need considerable more of them.
If your commander is at the front at minute 10 and you haven't gotten yourself a flak or two and/or a mobile shield, nor took the time to scout, then that's on you mate. On top of that, your commander was already at ~3k health, you were fighting beyond any sort of air cover, and your teammate above you was just sniped by corsairs but you didn't react to that until the corsairs were onto you already.
Sniping soft, overextended targets that don't have any AA is exactly what T2 bombers are made for. Just learn to bring 2 flak with you and build some scouts.
