Remove ship buffs? So we strive to increase renown for bigger boats but there are no perks?
I've never been in a group where anyone told me that I had to take their invite, their buffs or else. And I've never been in a quest or raid where I was denied because my guild don't have the perks and unless I have them I'm gimp.
The buffs are good as 1 hour buffs, such as greater elemental resists where you're likely to use a lot of SP (such as Epic chrono) and this takes some pressure off casters. But the impact of the different shrines are in reality minimal compared to gear. It's your choice to use it or not. Unless there's evidence of rampant denial to run quests without them I assume this has more to do about a feeling of OP or maybe having to wait for someone getting the buffs before running quest.
