Warning for future GS

Well, a GM could have at least checked the class of the person that was up there. (I believe it's also possible for CBs to get up their by having a hacker fly up there, use a summoning bag, and then the CB can assaulter his/her way onto that shack.) If it was a GS or a CB, then perhaps the GM could suspect that it's due to skills, assuming GMs even know how game mechanics work.

How about a hacking Gunslinger?

Guys; if you were running a game, would you rather be thinking 'oh, he is of this class, and they can get up there if they try, but hackers also reside up there a lot, let's leave a certain class up there although that person may have hacked up there'

or will you think that everyone up there = possible hacker.

Better to be safe than sorry
