Old Yorick just spammed whatever spell was up untill he was oom.
Current Yorick has a very obvious and visible window of power.
He stacks up his Graves (Giving you windows to trade with him while his Q is on cooldown)
Has a short window of power where he can summon his mistwalkers, which you can avoid by walking back ( his ghouls are slow and attack slow) or dodging his E.
Anyone who knows how to play a laningphase in this game knows new Yorick is not NEARLY as oppressive as old Yorick.
Also, you can avoid his W, Dash out of it, AA it twice (a lot of toplane champions will have either a dash or an AA reset) and walk away.
Not to mention his entire kit falls apart if you dodge his telegraphed E.
