A free company can have up to 512 members, but only 2 company actions could be used whether members like it or not.
I thought it would be neat to have platoons within the Free Company. So maybe 4 platoons allowed in a free company, up to 128 members each (or heck, even 512 limit wouldn't hurt). A platoon would allow 1 extra action on top of the already existing FC buffs to be activated. I imagine a restriction could be placed such as not being able to switch platoons until 24 hours has passed.
In my (rather small) history of having joined different FCs (across a couple alts too) usually just the EXP boost and/or MGP boost would be active and I know they will be useless for some members. So with the platoon feature, an example of it being put to good use would be a platoon that would help crafters/gatherers with a buff useful to them when the FC generally uses PVE buffs. Thank you for reading.
