Can I take as many Alliance gift chests that I see have 'Claim' on them?

Well those that you see are yours. Some gift chests are distributed to everyone in the alliance. However if you are talking about the store then you must be respectful to those who have put in work. (Mainly Donations) O also suggest that if you are not putting in your fair share to the alliance by participating in events or donating then you need to or go solo. But good luck in the wild as you tend to get burnt if you don't have bubbles. I'm an R4/R5 Co leader or our alliance and we allow noobs to leach off us but after a month they need to get involved more or risk getting kicked. Rule of thumb her, respect those who do the most work.
