And so the epic battle continues on the guild forum!!. theres not much need to add oppinions on this as it has been discussed alot, all we're really interested in is the result of the poll. As a refresh:
Fury shrine adds % to everybodies "fury caster" enhancement, which means everyone gets max lvl buffs which is great. On the other hand, there are many pieces of gear which give this enhancement, so it is more of a convenience thing, especially during hunts. At max lvl this will cost around 12k per hour (currently 1500 at lvl 2.
Tranquil retreat adds + 20 stamina to everyone in the guild. this saves people spending 4 fsp each to buy it themselves, especially as fsp are so expensive and out of the reach of low lvls to buy with gold very easily. This is however, the most expensive structure at its max lvl, 12, costing 32k per hour. atm, it costs 8k at lvl 10 and 16k at lvl 11.
