It may seem like a small thing, but in current configuration, everything you can use on olympiad, you need to obtain ingame. I understand that it may be frustrating to have to clean inventory prior to oly, but on all our servers also in the past we did not allow any custom items on olympiad. Having possibility on olympaid to have 4 talisman slots without actually doing anything and on top of that the weight+slot bonus is just too powerful in our opinion.
