Trying to find a player from my shard who systematically attack during everyone else payout

Sounds like they are playing the game right. If there refresh time is later then everyone else, they are trying to finish in the best position to earn the most rewards. I don't understand the issue. PVP is free for all, do what you can to come out on top, attack who is weaker or you think you can beat. I also do not do or believe in shard chats.
