Well with enought gold and amalgam ,and if your raid can clean it , you should be able to loot enought upgrade to gear 2-3 full green people into full epic.
Each open Box give you 75 stabilisations if you didnt unlocked blue , 50 if you didnt unlocked purple , and 25 if you're trying to unlock leggy.
So yeah in 3 weeks you can probably boost your guildmates by a huge margin
