you have to take profit because there's no room to put full value When you put less on a spot because someone 'overcooked' it i.e. How to avoid snipers is covered more in the next section, but once your GB reaches profitable levels at 1.9 (level 30 and up on most GB's, see list below) then you need to open 1 blueprint level at a time and ask the guild to take the profitable spots right away before they get 'sniped.' There is malicious intent and these people often have level 100 arcs or higher and are in it for whatever profits they can gain, paying in much less than 1.9 and making much more than 1.9 in return. The term sniper is all about people who undercut the value of a spot on a GB deliberately in order to make profits for themselves. Permission has nothing to do with it, you don't need to sign the Magna Carta first to be able to add to someone's GB's, the game allows it and as long as there's no malicious intent, what's the problem? A lot of people are confused about the term 'sniper' on GB's thinking it means anyone who adds to your GB without you asking them, or by getting your permission first.

It's not a sniper unless they have a level 80 arc and secured a spot on your GB at less than 1.9 value.
