You know whats even more frustrating to play against than a Yorick in lane?

You can try to destroy his turrets, but he'll hit you with stuns and turrets while your futile attempts to destroy his turrets are either not enough to kill it, or his turrets are immediately replaced because its a 20 second cd.
Destroying his turrets is the only counter play (not counterpick
)I've ever heard short of 4 man ganking him and even that he has enough in his kit to severely punish you for trying. Ganks from your jungler alone will just give him a double kill, and you cant just engage him due to his stun and his turrets turning a 1v1 into a 4v1.
So shouldn't he be terrible late game in teamfights when its not laning as a tradeoff? Well, no. His turrets provide good zone control and his damage is insane. Even their team is losing, he has no problem stalling games out forever until his team can catch-up by placing his turrets to protect vital areas they need to protect.
Anyone can play heimerdinger and still be good as long as they dont place his turrets in stupid places. A good heimerdinger is as scary if not scarier than a fed akali.
