As new player i think that Wizards Vault isnot exactly that good.
I have boosted 1 my character 80 so i can do those, but problem for me is that there is like 6 dailies where u need pick 4 if u want that box. And moust of them is WvW or pure pvp dailies.
And weekly i have done only 1 line for now. And special some reason need newest expansion. I have played atm only 2 weeks and bought thorn and fire expansions.
I think they should make it worth for peoples who dont own all expansions and dont necessary like make every day WvW if want those materials.
