i think olympiad gives u opponent depending on what points u have, so if u are for example around 20-30 points, u dont have to be worried about necro with 100 points, because it wont match u together (or at least it should work like that with enough ppl registring, dunno what happens if there are 9 ppl with 100 points and 1 person with 20, if he can get the farmer or not) about books for 3rd class, maybe not all books should be obtained by olympiad, but u should make sure they are tradeable, like they were in H5, so if u are lazy to do olympiad, u can still buy them from other ppl/heroes (gracia final system was bullsh1t, coz u had to farm for your own book if u wanted it) olympiad system matching was always random no matter how many points have participants why so many people worry about 3rd class book ? you need them at 76+, so in like 10 years
