trouble getting evan/aran books

When nexon made zakum instanced, they lowered the drop rates to level off the fact that anyone can go in at any time(which, in my opinion, is a step back in finding the books).
Chaos Zakum doesn't suffer this because it isn't instanced.
Also... just wait for hilla, since she gives plenty of books i heard.

Wait 2 months for my main attack in 4th job? pineapple no.
