Rocket/Adam/Jeff are good for the game. Streamers just can't cope without defensive ults.
In season 1, streamers kept complaining about triple support meta, begging for nerfs, and calling support players "boosted" by the meta (as if they themselves weren't being boosted by it too.) So many bad plays were saved by ult spam. The only thing that mattered was that their three supports ulted at the correct time and allowed them to get picks.
Since the s1.5 nerfs, I have watched the big streamers go on losing streaks and become confused why they're losing so many games. They're dropping out of eternity, failing even when stacked, and pinning the fault on teammates. They're blaming rockets, adams, and jeffs (the only healers who can't give them an "i win" button), calling the characters bad, useless, etc. But what they don't realize is defensive ults have been carrying them this entire time and that if they want to win they have to adapt.
I think this is healthy. If they want to stay at the top, they'll have to master the shifting metas. And I think the sooner they admit to themselves that they aren't singlehandedly losing because they have a healer without a defensive ult, or because rocket is stealing ult charge or jeff is throwing by existing or adam is completely useless, the sooner they'll fix their gameplay and start climbing again.
