Just as a direct (if tiny) point on this. There is now a system of tokens (random drops from mobs) that allow you to get your raid pots free so long as you have rep with certain factions
The pots are the 2 hour flasks so free rather than ~35g you would pay for a normal one. Only work in the full-instance 25mans tho (so not gruul or magtheridon)
The unstable flasks for blades edge/gruul aren't exactly expensive either though. A group of 5 people together can do the event and get enough flasks for a months worth of gruul raids for the whole guild if they've been doing daily quests.
