What Sion Needs
After playing Sion a lot recently, I've had mixed feelings. On the one hand, his champion design is really fun and even manages to make death feel satisfying, which is hard to say for most champions. On the other hand, his kit seems clunky and out of place.
Passive - This is probably the best part of the new Sion, but it needs a little work. The fixed attack speed and movement speed cap (as well as the inability to proc movement speed enhancing on hit effects) feels pretty bad. Since it takes so long to actually activate and disrupts the flow of a fight, it's relatively easy to get away, kite, or otherwise CC Sion so this passive is entirely useless. A little love here wouldn't hurt and might encourage alternative builds.
Q - My biggest problem with this ability is the concept of rooting yourself. Much like pre-rework Xerath, getting knocked back while you've rooted yourself into the ground is just counter-intuitive. I'm not asking for total CC immunity, but why even note that he roots himself in place if any enemy with a knock-back can slap him around like a ping-pong ball? People should FEAR the power he is putting into this move and attempt to run away instead of just moving Sion away. This is a massive hulking undead colossus who is standing his ground. Thematically, the self-root would make so much more sense if he could ignore those pesky knock-backs. MAYBE even knock-ups, though I admit that might be a bit too strong.
W - Eh. That's all there is to say about this ability. That speaks for itself.
E - I have no complaints here.
R - His most satisfying move but far from flawless. His turning speed could be raised just a tiny bit and it would feel leagues better. Either that or you could ignore DESTROYED turrets. Slamming into a standing turret definitely stop him but a pile of rubble? Come on, now. This would give the ultimate more uses in a game where you're losing AND where you're ahead where you can make plays in lanes that have been dominated by either team.
As it stands, it doesn't feel like there's any build path that works aside from full tank. A few small changes would open up new worlds of play styles that would make the game a richer experience for all.
then. Hecarim can R over a wall, so I think Sion can be given that extra utility too. Even Malphite
's R has that extra utility. Unstoppable equality, please.
