I finally understand why so many people pick Rocket Racoon
As a tank main, I used to be a bit annoyed when someone on my team picked Rocket, because I just felt like his ult wasn't good enough compared to other support ultimates.
However, after filling heals in plat lobbies the last couple days, I realised that when you are getting dived non-stop by tanky melee characters (Thor, Captain, Magic), if your other healer or your dps don't care about your life and leave you alone 1v1 or 1v2, playing Rocket is so much easier than playing any other healer. You literally don't have to worry about dive anymore and it feels so nice.
So, to the Rocket pickers out there, sorry for being a doubter, I get it now.
