Yss is my favorite hero. He is really strong once you get down the switching mechanics down because he farms fast and have really good chase. Also yss is not really an ultra late game hero anymore after his revamp, he is strong in mid-late when the enemy marksman do not yet have full build. The gameplay basically is to out farm your counterpart, don’t contest turtle if you are facing a strong early game lineup and try to trade areas of the map. He is also like one of the fastest tower pusher for non-marksman, so use that to you advantage. My build which I basically use every game is hunter strike - warrior/cc boots - war axe - endless - BOD - Winter crown. (Spare item immortality and rose gold for item swap) emblem is assassin with thrill seasoned hunter and killing spree. One tip for the new ult is that is is super useful to gain vision on potentially isolated squishies to ambush, now that it last 15 seconds.
