MNK and RPR would become meta jobs if people focused like you suggested, as they both have very short charge times on their guard-breaking LBs. Hell, I play NIN most of the time and I get away with murder (literally) by just tapping guard immediately after I finish killing someone with LB. So many times I can just LB someone deep in enemy lines, Guard for a few seconds and watch numerous stuns and binds bounce off, and then just shukuchi away to safety. Between potions, huton, and purify (if needed), it's pretty much completely safe *unless* there's someone on the enemy team with enough situational awareness to recognize that they could get a free kill on that BH5 NIN.

But NA players are oblivious. There's a *huge* "it's pvp idc I just want XP/my horsey" attitude problem with FL on NA servers. People don't want to learn or try and improve, they just want free stuff.
