I think those lessons may help every player, party, CP and Clan.
#1 Help your supports.
A good party for PVE and PVP need well geared supports as well. Of course the DD requires more gear because of the weapons, DYES, etc. But give the supports some love. Most of the CPs use the support when necessary: dailles, bosses, AFK exp but forgot them for timed zones and adena farm(Crisis, PI, TOI, Refinary, etc). So usually whem the overnight exp is done, each DD go solo farm exp/adena and the support just have to stay idle or try to find something else. Most supports try to invest some adena on DD dual class to try farm something but that make the main char weaker because of the investment on dual class and it will not be as good as a DD as main class.
Ask each DD to help a support on this instances when the CP break the afk exp.
#2 Don't trash talk at all
Limit to minimum communication when dealing with enemies. Maybe a few jokes here and there but never be agressive or go to the trash talk. Don't pollute the global chat with offenses and non-sense discussions. what you say, sooner or later will come back to you.
#3 Don't PK AFK players, even enemies
Don't try to revenge from real PVP: Sieges, Bosses fight, Garnak, etc hunting enemies AFK. The only excption is to pay back.
#4 Explain the expected mechanics
When doing any activity like dailles, siege, pvp, make sure that you explain the reason and why each member need to execute especifics tasks. This way it will be easier for everybody to understand, remember and repeat the task/action.
#5 Share the loot equaly
When getting loot make sure to share with everybody that participated. Of course there is no perfect division and sometime the random drop can be used because it is fair and can't be manipulated.
#6 As a leader, be respectiful and show class
Use the communication channels wisely and screaming in Discord/TS, etc doesn't help at all.
#7 When PVPing in siege keep your role and do what the ally expect from you
Don't just leave your position trying to score some points. Stick to the plan and follow the lead. If you job is to guard the gate, focus on that, dont roam without a good reason.
Screaming just show you are not a good leader and lost control.
Inspire your partie/CP by giving examples.
