After the champs in dire need (Poppy, Taric, Yorick), how about a VU for Malphite?
You know, I really love my boy; the Shard of the Monolith himself, Malphite. He's as solid as he's ever been in the top lane as a tank who's still able to dish out respectable damage and deliver those teamfight winning ults. He's as close to a direct counter as you can get to those auto-attack reliant fighters in the top lane. He was the champion I used to learn the game due to his relatively simple kit and I mained him while I leveled to 30 (and in ranked now, as well).
All that said, I saw a post on Reddit that linked me to the list of champion updates that you've done since the release of LoL and it had me thinking, "Has Malphite ever had a visual update/rework?" After doing some looking, it seems that the OG Rock (whose 6 year anniversary of being on the rift is this month) has never received a visual update only received a texture re-balance and has only recently had a minor rework to his abilities (which were awesome mind you, that whole Brutal Strikes update was rad). I feel like, as one of your original champs, this guy needs and deserves some visual update love! Not just his classic skin, I'm talking Maokai/Sion/Gangplank/(Fiora?) levels of update here, guys.
Come on Rito, for the rock mains out there. 
This may be a bit "noisy" or cluttered for a champion in League, but this thread has already been shown around a lot and is a good example of something that could be done with Malphite: http://www.polycount.com/forum/showthread.php?t=143736
