I do like the server changes. Generally, I had a steady 100ms or so ping, now I'm in the 30-40ms region. It always was a little annoying to be on a good connection, yet still have a yellow bar for the entirety of the game because of where the servers were located. And the west coast player tears are delicious... welcome to the last 6 years for any east coast player, bud.
I'm actually really glad that they added Dead Man's Plate in, as it really ties together my Tahm Kench jungle. Unfortunately, it's a very slow and fairly unstable start, but once you get rolling with Devourer and Dead Man's Plate (potentially with a lucky gank beforehand) then you become a bit of a juggernaut yourself. Round it out with some Merc Treads, Frozen Mallet, Spirit Visage, and a last slot to flavor (Titanic Hydra for even more damage and double cleave, Warmogs for the insane regen, armor or MR as potentially needed), and you tend to be the bane of anything you can catch up to. Since his ultimate's passive scales with health, you can be doing in excess of 200+ magic damage from that alone per hit, not counting a sated Devourer. ADCs are particularly delicious, as they tend to think they can take you... up until you bash them twice, stun, tongue lash them a few more times, then devour them. Cho'Gath ain't got nothing on this.
It's like a bad meme. "Hey, I heard you like devouring..."
His kit is also pretty solid all around. A near instant-ranged slow/stun, a multifaceted initiate/ally save/disable/huge damage bonus unaffected by Tenacity (as far as I know, only Mercurial can escape it... and it has a 10 second cooldown with no CDR) that can also disjoint movement abilities (I've snagged a Shyvanna trying to escape with her ultimate in mid cast), an ability that acts as a huge spot defensive bonus and provides additional regen during jungle clears/between battles, and an ultimate that not only gives him additional damage for building health, but can also act as a surprise gank from afar. Only real drawback is being unable to nom on the big jungle monsters, meaning the first red and blue clear are exceptionally painful.
On another note, has anyone really seen Fiora played much since her rework? Most melee top seem to shut her down handily, not to mention ranged, as her "extra skill required" kit means that people can simply mash buttons and auto attack while you're trying to be dainty and utilize your abilities to the fullest.
