I'm concerned about the treasure hunter/merchant pack even with the increase in price. As others have said, the relative cost of 45 RP (if we use market rates for RP items, then 50-60 fsp by my estimation) is very low compared to the benefits that it provides. If even one member burns a decent amount of stamina (75k) it more than makes up for cost incurred for the guild. Obviously this economy effect would be compounded even more for larger guilds, who can afford to gvg more frequently and run the pack for more members as well. I recall that the original rationale for not allowing buff enhancer to increase the level of treasure hunter/merchant was potentially adverse and unknown impacts to game economy, and I think this new pack should be considered with the same scrutiny.
I propose to either decrease the power or increase the cost of this pack. Right now the highest level obtainable for these buffs, excluding the 500 level exclusive Christmas buff, is 200/200 also from an RP pack. I suggest changing the cost to 50 RP and the buffs to 300/300 (and getting rid of the 35
RP cost 300/300 pack), which would keep the package relatively obtainable and still a substantial upgrade from the existing package. Alternatively, if the buffs are to remain at 400/400, I would recommend increasing the RP cost quite a bit, perhaps to 100 or 150. I am less in favor of increasing the RP because it makes the pack less accessible especially to smaller guilds, but it would reduce the frequency at which the larger guilds could run the pack as well. Obviously for this approach the 300/300 pack would need a price increase as well, perhaps to 45 or 50.
