Re: 5 things you want to see
1) Cap leads the team
2) Thor/Ultron confrontation - no Middle English in MCU Thor so just leave out the "thee" part and then Thor lays the smack down - don't nerf the Thunder God
3) Probability manipulation by Wanda - not telekinesis etc.
4) Hulk speaking
5) Cocky, wise cracking Hawkeye
