It would be nice if credo's were capped at a certain amount of extra quests, like 50
I know you intended to force people to rely on others to get every credo you need by increasing the amount of quests you have to do for every credo you complete, but all it does it make you create alts for it. If you have to choose between doing 100 quests, or just making an alt, people just choose the alt.
There's no real reason not to, especially since with alts, it's easier to delegate LP into certain things rather than being an all rounder, especially by using mass produced curios. For example, farmer credo alt, he can complete farmer with only a small amount of quests, and there's no downside here, since all the farmer alt cares about is farming skill. Meanwhile, if you have completed Nomad+Strider on your main, the 80 quests for farmer credo suddenly looks meaningless to pursue, when you could do the same thing in 20 quests on an alt with no downside whatsoever.
So, for people who don't want to make alts, because they are attached to one character, I think it's unfairly punishing and just gimps them for no substantial reason.
