I don't understand the whole "Lock" thing. My understanding is that ranged/magic does not interrupt casting.
While it doesn't interrupt casting that has already started, the game is programmed in such a way that inputs are ignored while certain attacks are being in place. If you're already moving, your fine. But try moving just as the Goblin pulls his crossbow out on you. In a similar vein, some JA's won't even register until after he's done shooting. I found this much more prevalently when roaming in duos on my PLD than in actual XP settings. I can see how having 4+ NINs spamming shurikens would lock a PLD/DNC right out of business.
This is it exactly. Have you never been locked in place after a mob dies with your weapon out because a mage cured you right as it died? The same thing can happen with stuff like the animation that happens on you when a ranged attack hits. This is how it would go:
1. I claim all 8+ ninja's and run, which with casting and trying to throw stars, they're easy to outpace and get a distance on.
2. I run a long distance, get into a corner, and cast my buffs to wait for them. When they reach 30 range, I start to spam engage to try and get my sword out before they get fully into range, which almost never works because shurikens are so fast. My sword comes out, and the ranged animations now have me locked with my sword out, unable to move, cast, change gear, use JA, nothing. Then i watch while I go from 1300 hp 800 before Phalanx wears off with 1-5 damage shurikens and 5-10 damage Ni nukes, then Phalanx wears and I die in less than a minute. Never able to move. If I've ever attempted to engage later, the shurikens would still lock me.
This becomes a serious risk on every ninja yaguda after the first 3. Of 4 I'll sometimes be locked for a few seconds at a time, but never continuously, and it gets progressively worse the more you add. This is only a problem really with ninja's because they spam so many overlapping animations between spells/nukes/stars. It also is a risk anytime you use a JA or spell.
