There is a need to have simple to enforce, yet fair raid rules to maintain a good environment in a guild.
The most important thing is to give everyone as best an opportunity to score some loot as possible, since they are contributing their fair share of coins.
The other priority is to make sure competition is fair for all, especially those that are capable of dealing more damage than others in a raid, as they will look elsewhere for better loot.
After our first TVI raid in FTB we developed the simplest raid rule we could, whilst being fair to all raiders, strong and weak.
We have since shared this technique with other guilds who have adopted and/or modified for their own purpose.
Anyone dealing damage prior to the announcement of Free For All (FFA) 24hrs after a Heroic raid is launched is ejected for the raids duration.
It's as simple as that.
As FFA Heroic raids typically last less tham 15 minutes, this essentially means anyone not able to make the raid FFA start time has 24hrs to sacrifice a 7☆ hero to the pigs and tie for last place loot on 0 damage.
If your solo hero gets to attack, no damage must be dealt to the captain to register 0 damage.
It also allows for practicing on pigs using retreats, and plenty of time to have a battle prepared for the announcement of FFA and score big in P1.
When preparing a battle for FFA you can turn data off on your device after starting your attack to make sure you don't get ejected from the raid if you do not pause in time before your squad is defeated, which would register your score when you have Internet connected.
Some people may be happy with other raid rules that involve more work in staging attacks, or single attacks to slow a raid down, but if they involve attacks that are not FFA it is not fair for anyone who is sacrificing higher ranks to others with less roster power.
Once any phase is defeated anyone finishing a battle in that phase will only have their damage registered for their personal raid damage, this damage will not be reduced from the current phase boss's HP. This is called overkill damage.
With this in mind raids can also be extended with an optional solo phase rule, allowing for more competition (both in higher ranks and lower) due to extra overkill damage.
Solo Phase Rule:
If you have pre loaded a battle that has soloed a phase, you must wait until the chat log declares that phase complete before finishing your battle.
If you have started a battle prior to FFA being announced and have completed P1 and P2 and are waiting in P3 to complete your battle at the commencement of FFA you must wait until the chat lof announces P1 completed. You can then rinse and repeat for the next phase.
This way when multiple people are posting solo phase battles they are all added as overkill damage, leaving more damage available in later phases, and those that cannot yet solo P1 have more opportunity to score damage in all phases of a raid because they are the ones dealing the actual damage to take a phase down.
Whilst we have many divisions in FTB and so are able to accommodate anyone's timezone with fixed schedules, another way to balance raids for everyone within a single guild (without excluding any region in the world) is to increment the raid start times by 6/8 hours giving a cycle of 4/3 raid times.
