No, sorry. Some of those splash arts you mention have NOTHING with them being hot or not, which is funny that you mention, because all those new splash arts are WAY more sex-driven than the old versions. Seriously with Kat's boobs.
It's not even that difficult to spot. Compare JUST Kat's face in Warring Kingdoms vs the new Classic Skin arts. Who does she think she is? Ezreal with red hair?
Should we talk about Sivir's broken spinal cord?
And what about dated splash arts that have NOTHING to do with the ingame model? Ask Phantom Karthus and Riot Girl Tristana. Who the heck are those assholes in the splash arts anymore? Not to mention... they re-release Tristana in 5.2 but can't even have her new splash for 5.3??
Then you have the Graves nonsense with the cigar. In some countries, owning a weapon is flat out illegal and offensive, so why not give him LITERALLY a Nerf toy weapon then?
Challenger Ahri just looks wrong. I don't know how, but they messed up her head somehow. There's this guy in DeviantArt who made a way better version... (http://dutomaster.deviantart.com/art/challenger-Ahri-508784709)
Imo, where there are some brand new splash arts that are just gorgeous, some others come out as flat out UGLY and for a while now I've been thinking the Splash Art department is the LAZIEST in all of Riot. They even are resorting to having a single splash for skins on the same theme like the upcoming Warwick and Ashe. That used to happen before, but nowhere near as often as now.
Someone needs to slap them and get them to do things. Seriously... they can't even release the normal Skin for Tristana even one patch later?? Even though they stated that "It's very easy to alter the old splash just by fixing some layers of the drawing"
Apparently not...
