The only time I'll consider Neji OP is if his mystery starts a combo, but it doesn't, so no he ain't OP. Like others have said, try and get around Neji. He isn't as tanky as Hinata of the same level so you should be able to shut him down real quick if you're faster than him. Get a healer on your team if you're annoyed by his mystery.

Also eXCUUUSE me, as someone who's struggling to memorize all 3 scripts of kana and uses romaji a lot, I'm offended :L

In a way, both :P I'm not entirely fine with people using romaji just because they heard it a lot of times in animes, it's a tad cringeworthy really; but I'd also appreciate it if people using romaji isn't downgraded to a weeb in general, because some of them are actually serious about learning the language.

No worries! When I first learnt Japanese, the phrases in our textbooks are all written in romaji. There are hiragana scripts on top but they're only there for the teachers' reference so I wasn't taught about it. For people like me, who only learnt communicative Japanese, using romaji is a transition to learning real kana scripts. I wouldn't use romaji while communicating with a Japanese person, of course. It's merely just a stepping stone until I can master kana.
