So I bought the Age of Discovery Adventure pack and i love the mercs but.. I am confused when getting this should it have unlocked DoV? I hit lvl 90 and 320 AA but says for me to go on in levels I need DoV can anyone explain this to me?
Unfortunately, no. AoD essentially gives your chars new functions--mercs, reforging, 20 new AAs, ability to buy DM items, etc. It doesn't add / unlock any new content.
No you need to either get CoE or buy DoV separatly. AoD was not a normal Expansion it was just a features pack.
