Support Sion, new meta?
I've been having a lot of success w/ Support Sion. He has high base damage on his E and Q in addition to their strong cc. The Armor Shred on his E also helps win trades and all-ins.
Mid to late game it gets rough unless you are able to really stomp early on since Sion really likes a lot of tanky items. That being said, depending on team comp he still provides plenty of cc during fights and a good shout can provide a lot of damage for the rest of your team. Also (this is depending on who you are playing with) he can split push well to get lanes snowballing during games where things are intense.
. Her bombs destroy you as a support) but unless you and your carry outright stomp the lane, then Sion isn't going to do as well as the game goes on.
