Ehm.. I have experienced this as a problem, maybe it was unintended but just adressing it here.
I'm currently playing a lot of Orochi, and the LongBow skill is one of the funniest and deadly things I've seen up until now.
Thing is, when someone runs out of range while I'm "charging" the longbow, he just walks out of range, the bow kind of glitches and turns around, the skill goes on cooldown *sad, takes so long to recharge while it had no effect*. Same happens as when I'm about to shoot someone, and he decides to climb up the ladder. The lock-on disappears and I can no longer fire at them even if I already had my bow out, nullifying everything and setting me back to cooldowns.
As I said earlier, maybe this was intentional, and if so -> you can ignore what I said here, it just felt bad :P
