Why Sion.

First of all, why play Sion in the bot lane, won't he get kited? And if you're going for a melee, why pick Sion over someone else.Here are some advantages that Sion brings over other champions:His passive is amazing when built AD. If you go tank Sion, more often than not, your passive can be ignored the longer the game lasts. With AD Sion, when you die, you will kill most enemies in 3 hits or less.His Q is similar to an auto attack. This is what makes ADC Sion work. Without charging, it has a range of 300. This scales up to 600. For comparison, Lucian has an auto attack range of 500. In terms of damage, using the Q without charging will always deal roughly the same damage as your AD value, which means you'll always at least have an AOE 'auto attack'. At full charge, your AD value gets tripled. This is why ADC Sion always deals so much damage even early game.His W is a shield with a health scaling passive. For each 10 minutes in the game, you should expect to gain at least 200 health. By 30 minutes, that's 600 extra health. The range on W is 500. If the Lucian is hitting you, you can hit him too.E is a single target armor shred, or an AOE slow + AOE armor shred. The slow is amazing to setup your Q.Lastly, his ultimate allows him to completely obliterate one or many targets. The charge time to reach the full damage is 3 seconds. Every time that it is up, you can kill someone in the game.Why Sion bot though? Once you learn to fill the shoes of an ADC, having a support with you allows you to setup your Q. Also being bot means you can kill two people instead of only one which means you get to snowball yourself, snowball your support and effectively stop two people from their team from playing the game. If your jungler also comes for a gank, well you're a Sion, so every time a jungler comes, you will get a free kill.Another important point is Sion's ability to flex into a position even during the game itself. If for example you have a strong top, mid and jungle. You can transition into a tank or a support to facilitate the victory. If you're team is really strong but lack AP damage, you can transition into a more AP oriented Sion build. (Having said that, Sion fits really well into an all AD team comp.)All of this combined means that Sion becomes impossible to stop when he pulls ahead even slightly. At worst, his kit is still good for the CC it provides, and given the absolute worst, death, he becomes a massive threat that cannot be ignored.
