This was discussed earlier in this thread around Page 5 but if it's not there for some reason

"He's a very solid and fun character with great movement. His only problem is that he tends to scale pretty heavily so you gotta spend time and figure out which combos to use, shorter ones often times tend to result in better damage. Its easy to get carried away and creative since he has so many tools and options. HD combos seem kind of iffy with him as well, easy to drop. Not to mention there isn't much he can do meterless in HD outside the corner or close to it. This is what makes him a weak anchor imo."

"I feel the same way in regards to his HD combos mid/full-screen, I run him 2nd right now but varying on the matchups I'm faced with, he goes first then Billy picks up the slack if there's any. The thing I've found with Robert is that whatever playstyle you have, the character next to him (whether he's 1st or 2nd) should compliment your style because I think it's the best way to get out everything from him & he has to many tools so he can do just about everything."
