Correct me if im wrong but EVENT ITEMS ARNT TRADEABLE?

I think that event items should definitly be tradeable cuase some people...Just cant seem to win events but can do jobs and try to buy it from other players.
Also there are players who are extremly experienced with events and therefore get all the hs(Doesnt really bother me that i cant get hs but i still want to be able to get the event items.)

So what i think would work:
The most obvious way to make event items tradeable

Make HS tradeable

Other ways to get HS then events
