those same people who say "too much damage creep"
are not wrong considering you can just look at the runes right now, but saying this is the worst state of LoL because of damage creep is a bit too, uneducated.
Remember Season 6? Devourer Yi and etc.? Those really showed the true power of damage. I'm talking about unkillable poppy and tanks with damage. The game had worse states with even more easily observable problems, the only reason people didnt freak out by that time (IMO) is because League also pulled a CertainlyT and brought back either OG features, made good changes to certain champions, and A .Sol.
So what's bad about now? The only thing that had a negative effect worse than most in 2016 was the change to towers (no laz0r and squishier towers with weird HP decisions, like inhib having more hp than the inhib tower). NOTHING I have seen during 2016-2018 was so broken that it was equivalent to Devourer Rageblade.
