These were the major things that stuck out from your list, Kris. The rest of the changes, I either agree with or don't know/don't care.
But these... first of all, what constitutes "high spots" these days? Flair and JBL weren't doing them when they were still wrestling actively, and I hardly think they'd be doing them now. Flair's biggest bump is falling off a ladder, but only from about halfway up typically. He does bleed a lot, but bleeding isn't a high spot. I don't think he deserves it. And JBL doesn't take hardcore bumps anymore and hasn't since he fully got into his rich Texan gimmick.
As for Flair, I don't think he deserves an over of 98. He would have if this were like... 1997, but he hasn't really been that "over". He's known around the world, but if you tried putting a world title on him in this day and age, people would laugh and call it ridiculously stupid, and for good reason. That's one thing about over - a wrestler can be popular worldwide, but his role or attributes not fit a title run.
The stats changes for JBL seem extremely unnecessary. The guy doesn't wrestle anymore, and it seems silly to want to boost his stats when I doubt he's going to be better NOW after he's been semi-retired for quite a while than compared to when he was world champion. He never deserved 94 in charisma, even in his prime, and certainly not selling of 79.
