Yeah I feel that Zenyatta stuff, you ult and go forward, when you look back there's no one with you to cap anything. :/ Solo I usually go for D.Va, I can still help by tanking and I have enough damage to be offensive sometimes (no wonder she's the one I played the most actually) and I find it quite easy to hit with her gun when she's outside the MEKA.

Yesterday I killed 4 in a row outside the meka (all of them were together) two times, and a triple kill with the ult on the last round. Stomped.
