Lets talk about "Unpopular" Champs Galio, Karthus, Poppy, SInged and Urgot

Well, what can you say about these underplayed, unappreciated champions but, wow. I mean there is plenty that can be said about all of them and here are my thoughts on the least popular five as of recent. There is just something to be said about each of them. But lets just start from the bottom of the roster according to Lolking. The bottom most being Galio, the one shot gargoyle whom's ult can change the tide of a team fight in seconds if they dont have some kind of cc immunity, but otherwise weak if not against an ap champ, and at most there may be at most 3 (If mid, support and if top or jungle plays an ap). But most likely there will be two or one seeing as Ad mids like Zed Talon and Yasuo are are quite prominent in todays meta. And while he has burst its only on one ability which is on a decently long cool-down of 7 second whereas with Vel Kos who spams harder than the old Ryze and can dish out 2 the damage, and a shield which helps tank more, but it only does so much vs nuke mids no matter how much resist he has. Next is the old Death singer himself Karthus who's special traits are dying and making people rage across the map with his ultimate. A spam-able q which does nice damage a large slow wall and an E that even the derpiest of Karthuses can be skilled with by just walking in. But death is a reward with Karthus, spamming left and right ulting and destroying a team all while at 0 hp. The only differences between Karthus and Sion is Karthus can't move but can destroy you across the lane, and cant be countered. The moment he dies your at his mercy, and his skill( If his or her skill is present). Now Poppy, the Demacian hammer of wrecking. This little bundle of pain is actually quite good, and I cant understand why poppy isn't more in use in the meta today, with a q that strikes like a nuke, more so if you have a sheen, a w for disengage, engage, tanking, getting to lane looking shiny it does it all and a E that closes gaps and can stun, its two champs capabilities combined and mix it with Q and W and all of a sudden the tacked person has a large amount of damage surging its way into their face. Now lets get to the bread and butter of a poppy, her ult. Her ult is a combination of things that makes good champs great, combine Olafs ability to not be stunned with his ult, with the negating damage and damage buff of Alistar but better since it also makes her ap damage stronger and being able to single out that one pesky champ like so many champions wish they could do, all in one powerhouse ult, whats not to love. And how about Poppies passive? Cutting damage IN HALF if it exceeds a percentage of her health. Period. No questions asked. A Cait ult? Half damage. Karthus ult? Half damage. Garen ult? Cutting even the unstoppable true damages damage in half is just mind boggling. Does this not seem broken enough?! Poppy is so strong and is yet still overlooked by the community unjustly. Singed, the flipper flapper of the rift, the first thing many people think when they think of Singed is "I hate that champ so much" Singed is a tricky champ, one game you'll see a Singed running behind turrets getting double kills off of the people who so foolishly tried to pursue him in battle, the next game hes 0-5 ten mins in, feeding top and jungle. With a Q that has left a rule of never chase a singed to a E that has left many champions and summoners frothing at the mouth at how good or bad the play was. While the w isn't game changing, its annoying for people in the process of running or chasing a Singed. And his ult, the rising kettle which resembles players who are about to lose their gaskets as he charges in and wrecks havoc on the enemy team with regen and stat boosts and...Speed boosts... The Singes escape from all but the strongest of cc and nukes and still has health left to go back to lane with. Singed is a decent champ as long as he has a decent trolly player behind him. And lastly Urgot...Sigh The champion of which is the figure head of ridicule left and right by many and all, from the pro to the scrubs, from the try hards to the casuals, he has been shown so little love and affection that even he feels the endless torture. I mean he has been in the game since before even season 2 and yet still getting little love or recognition for his time spent in the league. So many champs, even among the unpopulars that have gotten more love. I mean Urgot has been in the league since almost the beginning and he has all of...what? Three skins?! And one you cant even get until the Vaults release it. So actually two skins. Zac has that many and hes barely a year old. But I digress. On with his mechanics Urgot is, in my opinion a great champ. His passive reduces all damage on anything he hits, which could be life or death in a 1v1 situation and can mess up a champ if they are not careful. A Q that does quite a bit of damage and can do it over and over and over again and it resets his attack animation so in essence its a secondary empowered auto attack that is followed up before and after it and it off once again as long as nothing gets in the way, which is where the E come into play. His E Not only lets his Qs fly over anything and hit its target head on, but it also reduces their armor by 20%, and stack that with a black cleaver(since it does Physical damage per tick) it can completely trash a champion regardless of their armor. His W can be helpful, but its honestly a tad week, it should probably scale off of ad but eh at least it now scales off of mana. and the slow it gives is really nice for engaging especially if you build a Frozen Gauntlet and force the fight. Now I personally feel his ult does not suit him. I mean I don't buy that Urgot is a marksman who does not even feel like a marksman, but a bruiser , and his ult does not help that notion, putting you face first into the enemy team with all of 80 armor and magic resist and a snare, honestly this does not strike me as marksman nor and "Executioner" and it feels out of place and inconvenient in a team fight. Well, that was my rant on the least popular five, and dont get me wrong I love all of these champs but I was mearly stating my mind on each of them. What do yall think? What would you change? Do you enjoy these champs?
