I can agree with flux about Rashid i didn't notice any difference with Rashid after S2 update but no meterless wakeup made my life easier.
I dabbled briefly with Rashid in S1 and am picking him up more in S2. Doesn't seem terribly different to me either but I do like that H Mixer seems to hit more consistently now. He also got a few new fun combos with the juggle additions. But yeah overall it feels like the biggest change is that everyone is basically living the Rashid life as far as DPs now, which for a guy who plays a pressure game generally that plays in his favor.
