Congrats on making Cav!
Congrats on Cav, and as others have said, Hulk's not a bad pull. If you're going to survive in this game, you can't be hoping for "god tier" champs every pull. You need to be happy to get useful champs, and Hulk is a useful champ. Poison immune science champ that hits like a truck and has some interesting synergies.*Most* of the champs I use every day are not top tier champs. They are useful in the content they are used in. Moving forward, that's what is going to matter most to you as you progress through Act 6 and onward.
