Its because its the fighting guild that they should ask for weapons. The crafting guild asks for crafting tools. The service guild asks for "service" tools. Even the mage guild will ask for consumables. And all 3 of those will also ask for you to clear out enemies. Its literally JUST the fighting guild that doesn't ask for any kind of crafted thing, which is strange.
Also about the "powerful races": I get Dragonkin and Seraph more often that ANY other race when the exotic guy rolls around. On the other hand I've still yet to see a single Nereid in my game at roughly 70 weeks in. And as I said in my post, Dragonkin and Seraph are among the strongest races in the game. So its definitely not because they are "rare" that they are powerful, and also not a cheat to start with them since they are so easy to get. Bare in mind, this is also with no upgrades in that area.
I'd just like to see races be a bit more balanced. If the dev already intends to do that, then thats great. As for the fighting guild, its not really a big deal, just really bizarre that every other guild, including the crafting guild, still needs supplies occasionally but somehow the fighting guild doesn't? Particularly when fighting is the current least profitable way to play the game.
