So, since the removal of Executioner's calling the AD champs of the game have literally nothing to apply grievious wounds
Which means nothing, because Ex Calling was an incredibly weak item. In any situation Calling could be useful, there were always better choices.
All healing in lane can easily be applied around the 1.5 second wounds duration, which made calling almost completely useless during the lanning phase.
The 1.5 second duration also means you'd have to focus Mundo to counter his healing, which is just an awful tactical choice.
The only thing Ex Calling was any good at was shutting down life steal or spell vamp in a 1v1, but armor and MR do the same job better anyways. 50% less damage inflicted means 50% less healing via converting damage to healing.
Except with resistances your also taking less damage, where with wounds you'd still take full damage. Not to mention Thornmail obliterates life-steal significantly harder than Calling ever could.
also doesn't help that luden's echo just came out, the ap's are just to strong at the moment
Luden's Echo is the replacement to DFG.
That's pretty much a 0 sum thing, not a massive buff to APs.
