Turrets are actually very strong

It's just that champions like ekko/riven or any other POS that can get shields and dashes every few seconds is making them look weak.

If malphite towerdives with ult and misses at level 6 then it's your kill but too bad this doesn't apply to someone like ekko who can miss their Q and W and just auto you to death then ult or E right out.

P.S. I hate ekko
