Following up on twistos comments, I think it is clear that most people are going for the dungeon 1 and 2 sets (tier 0 and 0.5 respectively). To this end it has to be made abundantly clear to all involved that to upgrade from one to the other is a class based affair. As it is clear that raiding 20 man instances is not going to happen in the foreseable future the tier 0 to 0.5 questline, or intense PVP grinding will be the only way people can get epic armour. It should be said that you can't upgrade the the Wildheart if you are a rogue, Elements if you are a hunter, and Magisters if you are a priest. I suggest that people focus and preferentially take their classes set armour if you want to do the tier 0.5 upgrade.
I also want to make it clear that whilst I do enjoy going into low end dungeons, the guild should preferentially be grouping with similar levels. Even if that means using LFG to pick up a few strays to make up the numbers. Most of the dungeoneering I do is in PUGs, and as such has allowed me to develop my play style and learn a great deal about what works and what does not.
It should also be noted that you should prepare for dungeoneering, and this means knowing to a certain extent what to expect. Do not ask to be brought to a dungeon that exceeds your level capability. You will bring sufficient health + mana potions/candles/anhks/arrows, running out is not an excuse. We all know how many we need, and if you ever run out make a mental note to bring more next time. Also bring other items to make the run easier. As an example, I bring an array of weapons and a spare set of armour. I also bring an array of weird and wonderful potions for resistances, invisiblity, armor and invulnerability. Anyone who was in BRD the other night will agree that the invis potions saved the day allowing us to progress to the boss fight.
Two final points. You will have your skill set up to date, and there will be an agreement layed down over need and greed. It is acceptable to need item upgrades that can be used right away. It is unacceptable to need items that are consumable, components of enchanting/alchemy/smithing, or potentially valuable on the auction house (boe epics). If the loot is potential bind on equip vendor trash have an enchanter de and roll on the shard.
Read this, and agree to it otherwise I shall not be able to help you in the future.
