He shouldn't turn heel yet, one day yeah but not for quite a long time in my opinion, people want to cheer him not boo. He should be an edgy face though not a complete straight babyface, the heels should go hard with him, even personal at times and he should bring it back with some hardcore shoot promos and also some violence. At the beginning it's fine to be happy, but I see where you're coming from, long term you want a bit of edge too, but I don't think a heel turn is the way to do it, people REALLY want to cheer him at the moment. I wouldn't turn him heel for years yet. There's some good feuds he could have, MJF is logical. Haven't watched regular for a while but even heel Jericho has potential for a good match, they had a little real life tension, they could play off that, would be an easy sell and both can cut good promos, Colt Cobana feud could be golden after the real life drama, Pac, there's a lot of shyt they could do because the matches are fresh. Give him a full long face run and eventually can switch, but it would kill the buzz to do it straight away, people aren't bored of him yet, he's just come back.
