I love killing T3 Caps and Thors with my Wasp .. and i even killed some Apocalypses with her.
I still have this CTP of refinement from Hulks uni in my invent and sometimes i wonder how annoying Wasp could be if i give it to her since chars without pierce often have a very hard time to scratch her.
The number of characters she can kill is very limited compared to Angel. I loved using her when I didn't have my Angel built yet. But Angel can sweep teams compared to the 1, or 2 if lucky, kills that Wasp can get.
