Jericho has been mostly given the role of pushing younger talents, but would be nice to see him win more matches. He has given some 5 star matches the last few months and him with CM Punk will always be a treat to watch. Jericho at one point couldn't even walk due to some illness some time ago and doctors said there was no hope, he got better thanks to DDP Yoga and now in the best shape of his life.
There's also this new guy called Ryback who is just a Goldberg wannabe, the crowd even chants Goldberg! in his matches lol He is as boring as John Cena if not more but he does quite the strength like he shows here. Other new characters you will see are Big E Langston, Fandango and Damien Sandow to name a few. The show is much better compared to like 2010-2011.
Btw the latest superstar to come to RAW is Mr. Perfect's son Michael McGillicutty, now changed his name to Curtis Axel. He was introduced by Paul Heyman as the next big thing. Gotta love Paul, cuts some pretty awesome promos
Also you can't expect anything similar to the Attitude Era now that the WWE is a completely different product but they still have some epic matches and promos here and there.
