I know this is almost impossible, but hear me out...or...read me out.
Take a look at some skins like Infernal Nasus, Project Yi, Dunkmaster Darius, Eternum Nocturne and others, and compare them to:
These skins above, and maybe some others, are not worth 1820rp currently.
I'll talk more about the Demonblade Tryndamere because that's the one im more familiar with.
The W is the same chicken.
Does not have new animations on the E also basicly.
Poor animations on the Q and R.
HAS NO RECALL ANIMATION.
It is just not worth 1820rp. Why won't riot just update a little bit those skins? Or just put them 1350rp or if you want 1500rp as an old-legendary skin.
They are just not worth that rp sadly, because i really like Demonblade Tryndamere and others.
