I could get behind a free company perk system.

Honestly though the thing I would want more is really nifty upgrades to free company halls that accomplish the same thing.
ie:
Buy/construct a crafting wing where all the guild level synth supports can be obtained. for the standard nominal fee.
obtain an aether node or crystal that allows for direct teleportation to the hall from any where in the game world.

A Teleportation whatsitsmadoodle that shaves a point off of all teleportation costs for members. Upgradeable to allow for the slight reduction in the gear damage penalty to a home point after being ko'ed.

A practice room with dummy's for the practice of combos. And or real live fake monsters that can used to learn attack patterns and formulate or refine strategy's. Upgradeable with a Sparring mat to practice pvp and to settle disagreements the gentleman's way.. With bloody combat.

The idea of going into a company hall to be greeted with the sight of trophy's of slain monsters or armor and displays set up for/by members. Then seeing people working away with crafting or working on the mechanics of there combat skills makes me smile a bit.
