I think most players only have 1 or 2 ways of getting in on people to do the 1 combo they can spam out, when Sim zones them they get upset. I used to enjoy playing against Sim before he was my main because I had to out think them to get in to do the damage, but once in it can be over fast.
I know the original question was not serious, but obviously having a low stamina character is not cowardly, lose concentration for a split second and it’s probably over.
If I was introducing someone to fighting games who wanted to improve, I’d tell them to pick Sim so they learn zoning straight away, I think he’s the best guy for learning good habits because you get punished big time for being in the wrong place, can’t rely on spamming, gotta focus. My opinion anyway
