Avoid getting locked out of rewards?

Guild Switching Prevention: Some guilds have been using guild switching (or hopping) to participate in far more raids than should be possible if its members all stayed part of one guild. With our previous update we attempted to stop this unintended behavior by making players that switched guilds ineligible for raid rewards for a 48 hour period. Unfortunately this change was not succeeding in a manner we were satisfied with. With our recent update, we are removing the 48 hour ineligibility for Raid rewards when switching guilds and introducing a new change. The maximum Guild Bank Coins that a guild can earn per day is 30k (210k in a week). We will be tracking individual player participation in each Raid, retaining the summon cost for each Raid participated in, and stop providing raid rewards to the player after he/she has participated in raids that exceed the limit of 210k per week to summon
