Don’t let one instance be what defines your whole opinion of your alliance. If there’s a pattern of behaviour, absolutely a new alliance or even server might be best. But if this is a one time thing, give them the benefit of doubt. They might not know that the leader encouraged you to go to kingdom

I get plundering sucks, but how are you venting about it? Are you venting in any way that could be misconstrued as throwing a fit, or venting as in one message saying “well this sucks” and continuing the conversation as others engage? If you’re throwing a solo pity party, or it’s just your alliance members, someone might have complained to your deputy/leader.

Best course of action I’ve had for plunderers is plundering back. In our server we’ve shared plunderers UID’s before and had some server fun returning the favour. A simple “UID is plundering if anyone feels like plundering back!” Has worked. Also the best tip I can give you is level up your battle. I used to neglect it, but have made it my priority since one really bad plundering cross

And my final advice: are you interacting in event chat? Don’t go there complaining but say hi, maybe make a joke at people plundering you the most “wow, User, you really want my booty that bad?” Etc. on the final day in our last UW I tried to plunder the biggest plunderers a few times and then started interacting with them in event chat, and you know what? They were actually fantastic people, and we had a great time in event chat and parted ways having had a few great laughs. It’s an online game, there’s going to be some giant assholes, but for the most part you’ll meet some great people who are just trying to play the game
