@Retired Guy yes, that's how it probably works and why that perk is fundamentally flawed.
Bullet notes why the perks are fundamentally flawed:
> Guild feature that only provides personal benefits, hardly any benefit for the guild in GbG, GE or GvG (neg. discounts of so few percentages are a twisted early April fool's day joke)
> Bonuses are underwhelming bad, many times better temporarily bonuses are offered both in boosters (20% att%) and friends tavern (30% att%) never mind the fixed bonuses we can earn anyways
> High costs, low reward if any reward at all, chances are low, bonuses offered are low and discounts are ineffective low
> All above stacking up against perks as more a burden for some guilds and inviting infighting for little personal gain, while not benefiting the guilds in any meaningful way
> Encouraging 1-person guilds and more fracturing of guilds. Completely defeating its own purpose and in extend harming the purpose and meaning of guilds in general
Solution bullet notes:
> Guild benefitting perks only, this encourages guilds to explore the perks and deciding up on an group strategy in GbG,GE of GvG rather then seeming personal gain
> Removing the ridiculous 30 contribution limit, it's only a obvious cheap money grab that'll end up as an unintended nail in the GP coffin
> Universal resources for pointe, EG 3fp, current age goods of choice, 100 diamonds (not that sneaky increase to 120 without improving the points), medals (giving finally another use for them), prom, or and other special goods from AF and forward player's choice which to use
> Costs depending on number of members but also an slight improvement in strength of each perk for every additional 10 members to encourage larger guilds
