Viktor is a case study in nerf creep.
"Keane believes that his current popularity is the inevitable product of the continuous nerfs to his competitors. “Viktor’s one of the champions that got into the metagame after all the top-tier champions like Ahri, LeBlanc, and Zed got nerfed," he says."
and then the article abruptly glosses over the point
'It’s all well and good to look at how Viktor became popular, but given how unique he is as a champion, it’s hard to describe exactly how he fits in the meta.'
This is glossing over the problem like a politician.
If you are in a situation where Viktor's silence was removed and Urgot without reworks is now meta, despite us knowing how terrible his kit actually is and how you had to implement the fog of war nerf to keep him manageable, you need to rethink how many champions you had to remove from viability to get to this point. (Veigar, Eve and Kassadin being the most recent examples)
Something has to give, they are too careful with the buffs and nerfs, and extreme nerfs only happen to champions who weren't top-tier to begin with. Say what you will but Kassadin's rework and nerfs were years in coming, but should have happened all at once and should not have resulted in a 450 range ult.
The removal of silence and the over-reliance on skillshots has got to stop. They make some champions too easy to beat and others way too mobile. The mobility creep, outside of making stupid designs in the first place that were designed to be flashy, is a direct result of not biting the bullet and removing Flash from the game years ago and then nerfing anyone with enough damage to counter it since.
And now we're back to top lane resembling Season 3 again, just with more blinks and the same amount of tank. I'm still forced to take both exhaust and ignite to compete top with normal top laners and give up flash entirely, and buy twice as many wards/potions as my opponent just to break even.
It's time for the nerf creep to stop cold and six months of hard buffs to occur on champions with little to no mobility, and time to revert to older versions of Eve, Darius, Talon, and I hate to say it, but Kassadin too.
When Katarina is the premiere example of your snowbally carries and isn't forced to build banshee's veil as a core item, something is seriously wrong with your overall vision for the game, to say nothing that Flash exists after five, nearly six years.
