We have basic rules that must ALWAYS be followed at all times.
Our rules are always changing as we progress
1) Listen to your superiors
2) Always perform to your best ability in raids, which means you MUST bring flasks/food buffs and speed potions to every raid.
3) Always know the tactics to each boss encounter before we attempt it
4) Always respect each others opinions
5) Turn up on time to each raid and accept and decline each raid invite (on calendar and in game)
As trial you need to stick to this things very strictly (flasks etc.). If you are a Raider and you dont follow these things you might get a warning on officer note. If you keep getting in raids unprepared and if you keep ignoring the Calendar you simply get a guild remove on the third warning.
