Best Tech Champ to use my Rank 5 ticket to help with Act 5 Chap 4
I have a rank up ticket and wondering what tech champ would help me the most in Act 5 chap 4.
Options are: Nebula, Doc Ock, Punsiher 2099
I already have Star Lord, Rocket Racoon, SpiderMan Stark Enhanced Rank 5.
Any advice would be appreciated (I actually have two tech rank up tickets so could do two of them if I need).
