You can't see staff tags anymore on PC....It's been like that for a month now so idk how you can see them o_o.
Anyways, that is not hacking in your picture. You can clearly see that he is at 1.5hp. That's horse blocking like Tyler or someone said earlier in the posts.

I'm not in Nerv but I've seen them trying hard to get 1k hours for the past 2 years...Also respect your elder guilds :]! They're one of the few guilds that was actually here from the beginning.
