4:10 It provides Groot with damage reduction as well (pretty sure it also gives Groot more HP, like how Scarlet Witch gets a passive 15% damage boost with Magneto on the team.). I personally never had issues playing Rocket when I didn't have a Groot or Punisher on the team. I never really rode Groot, because him being so big and slow, I was an easier target to hit, even if I did get damage reduction, I'd rather just not get hit at all, plus I can better line up my heal shots from behind everyone, instead of being on the front-lines on the tank. As for Punisher, that is a great ability for Punisher to have (probably the best in game atm), but you're still healing, reviving and amping everyone all the same without him. You also didn't mention Rocket wall running, which gives him pretty good mobility, or him being able to hover, which I used a bunch to play keep away with Magik and Hulk.
