Karthus ever gonna get re-worked?

I know they changed around his visuals, but they never touched on his abilities at all, mostly his passive. Although it is pretty unique, it's virtually worthless these days. In the past when you laned against Zyra, Malz, Ziggs, Xerath, Syndra, Veig, etc, if they all in'ed you, they took the chance of dying to your passive. Now? Talon, Kat, Ahri, Azir, Lebroke, Akali and basically any ADC aside from Ashe and Varus can destroy you and just leap to safety. The ONLY thing you have at your disposal is your ult; and how virtually useless is it to hold onto your ult until you die to actually use it?

Not to mention all they really have to do is jump to a second tier tower. Now your passive, AND your ult are completely negated. On top of that, since mobility is the big thing to Riot these days, Karthus has absolutely none. I could see the designers were thinkin of it when they made him "Well his passive makes up for being easily ganked". Nope. What jung these days can't kick the hell out of Karthus and jump away? Lee? J4? Rek Sai?

Come on Riot, give Karthus some love.
