Regarding Grand Company leves and the seals you earn in the grand company.

I feel the GC leves while very nice and fun for exp, is very low reward wise, 40 seals (80 now durign the festivites) I feel is way to low, and I suggest boosting this up to at least 100-150.

Why?

New players, who joins a company as soon as they can will first want to save up 3k seals to spend on a chocobo license (and at this point they wont be able to do the r45 dungeon quest for a big chunk of seals).

Then they need 1-2k seals for any company items they might want to use while leveling, plus the DoH and Dol manuals which are 200 seals each for a one time use.

Even for old players the seals earned is very low as very few would be willing to spend most of their leve allowance just to grind seals trough gc leves just to be able to get the level 30 gc items or manuals.

How does this connect to guild marks then?

Add DoH and DoL manuals to the list of items(traits NPC) you can spend guild marks on, since every leve theese days floods us with guild marks and there isnt much to spend it on thats of real use.
This would also make sense to have it go hand in hand with the classes that they are meant to be used on, since players who mainly level DoH or DoL classes are pretty much locked out of GC rewards.
This also takes away some toll of grinding GC seals and lets people more freely choose to spend seals on equipment items and also doing regional and local leves with their allowances.

Thank you for your time reading =)
