Late game crafting thoughts along with pay-for-cosmetic items.
The problem with the game is that there is not really anything to do after you'd built everything, killed every beast and mined every ore, craft every object and so on. I think there should be a BIG overhaul on the late game crafting (armor and weapons). You should implement armor and weapon sets, with a distinct look, that provide some set bonuses when equipped (It's nothing new, I stole the idea from Diablo 2 but it could work perfectly in this game).
Have something like
TIER1 - Crafts using basic resourses Iron/copper/wood, leather), have some tier 1 sets that provide a small boost in a skill relevand to your role - hunter/fighter/crafter/farmer/merchant/etc
TIER2 - Crafts using advance materials - Steel/Hard Leather/etc. Have the TIER 2 sets look cool and proide a moderate boost in stats
TIER3 - Crafts using some rare stuff - gold and fated stuff, also maybe some insanely rare drops from beasts or from fishing or whatever, quest rewards, etc. Give the TIER3 an elite look, and have the sets offer a significant bonus in stats.
Make it so that you can pay a custom look (purely cosmetic) for each TIER above.
Also mounts - let us ride stuff in the game and have paid cosmetic mounts. Armor and custom colours for horses and mounts
