I bring a lot of fire pots for the raid. I supply some of the mats through my own farming, and Maube supplies most of the others through collecting donations to the raid bank and her own farming. I try to bring between 45-60 pots a run. That seems like an awful lot, and it is. Three stacks of dreamfoil and six stacks of elemental fire is a noticeable investment in farm time, not to mention about the limit of my available bag space :-) Maube brings a few stacks of her own to hand out, in addition to the materials she supplies to me and some people maintain significant personal stockpiles for their raiding needs, like Relikk. All those pots usually still are not enough to give everyone in the raid the required minimum of fire pots for a single attempt.
In past weeks, many members of the raid have been bringing their own pots. This is a good thing, something I want to encourage, because it's very difficult for the raid bank to give everyone enough fire pots. If something goes wrong and we wipe, forcing a second attempt, even if everyone only uses the two pots per attempt that you're almost assured to burn through, that's 160 fire pots. Trying to supply that much in the way of mats will burn the steady contributors out. I would prefer it if the raid supply serves primarily as a supplement, providing pots to only a handful who were unable to pick up their own pots that week, and acting as a reserve in case of a wipe like the one we suffered this week. We'll be in a much better position to ensure Ragnaros gets clomped if I have 40 pots right at hand to pass out, to go along with the 15-30 that can generally be brewed from the materials individual raiders happen to carry in their packs.
