The Proof that Riot hates Karthus

"Wall of Pain’s slow now decays.

Another huge beneficiary of preseason, Karthus’s reliability with Wall of Pain makes the follow-up onslaught of Lay Wastes less ‘dodging and weaving’ and more of an inevitability. Karthus still retains his immediate catch potential, but now has to rely on some slick predictions (or follow-up from teammates) before dragging his prey with him to the great beyond. W - Wall of Pain WALL OF DISCOMFORT Slow drops to half effectiveness after 1 second"

Just when I thought wall of minor effectiveness couldn't be any more useless riot proves me wrong.

Not only did you take away mana pot and for the only champ in the game that can run out of mana with maximum regen items, but you also didn't compensate him for that in patch 5.22------ 5.24.

The you a his W the most useless ability he has since it has been neffed absolutely to the ground since season 2.

30 champs 100-0 Karthus at level 6 wall is the last ability you max because E at least give you some form of mana regen; so now the only way I have to escape getting chanced down, because my farming pushes the minion wave under my enemies turret and puts me in the kills zone with no dash or other escape root makes my farming a determent not a strength, is a one second slow ward 30% slow is worthless but if it was 80% at all levels their would be no reason to level it at all because it has no other scaling other then size.

Karthus the only champ with a ward that last 5 seconds and cost 100 mana built in to his kit. [zombie-brand-facepalm]
