I consistently get positive post match messages in BlazBlue and Persona 4 Arena, I think it has something to do with how ArcSys designs their mechanics to be as unsalty as possible, the charming artstyle, the personality of all the characters and the lack of a fuckin' taunt button has something to do it with i'm sure.
I did go into BB and later P4A when it deigned to show its face across the pond after a fuckload of UMVC3 which may as well be renamed Salt: The Game everyone is post match raging messaging at you, ragequitting, spamming taunt after the match is over and a load more crap I cannot be arsed to deal with anymore.
I have to blame X-Factor. As hype as it is, a blatant comeback mechanic is by definition something that is going to rustle so many jimmies.
I have to perhaps take an exception with P4A because I assume the majority of people who bought it played Persona 4 and bought it to play their favourite characters and run through the story. Now anyone who has played Persona 4 will tell you that every character is great and liked by all, so if people get wrecked online by someone the fact it was done by best character ever Naoto Shirogane softens that blow immensely.
I mean people (mostly) don't even rage when you land an instakill on them... Which I do on spam happy Elisabeths rather often because she can inadvertently kill herself with Shuffle Time. Every one of her protectiles are so stupidly unsafe and I mean UNSAFE, I mean twice as bad as Vergil's Stinger unsafe.
I played a few matches with this one guy and he was using the EX'd fire thing to bring me in close from fullscreen for the ambiguous low/high hit. I managed to read it perfectly the once, popped back up and immediately did the instakill. Then we had a discussion about favourite characters, how Elisabeth is ironically Garbage Tier and the inevitable Inferno Divider reference came up because they just ripped it from BB and gave it to Yu and it's as aggravating as ever.
I never really noticed how over the top Yu's start up for Myriad Truths was until that match... He slowly points his sword at the ground and plunges it through his Persona card while dropping to his knees. BroSwagtagonist reborn.
