Just met a perma invisible NIN in Frontline while attacking

[hynaku]

Yesterday saw a machinist on the other side of land mass targeting ones and shooting thru it or he was inside it. Also yesterday saw a ninja where every attack did to him did zero damage and heavy didn't even work on him. Seen a bard other day fully heal them self with no other members around them and was running away at the time. Another time tried to attack a ninja and said invalid target wouldn't let you attack him but he could attack you. Saw ones using aim bot in pvp. Yoshi need to start looking into all these cheaters in pvp because it is wrecking it for all others. I don't think that's a bug because have seen it to much on blade and soul in there pvp. Where a summoner and there pet would be permanent invisible after using the skill. Also seen that used on Aion in the past and here in frontlines.
