This is a very good time to fix some mistakes and make some good judgment calls on potential changes that have not been outright announced.

EDIT: Personally I find Sej's W feeling unimpactful. But Sej mains have a right to say what she could get from this update, since they pointed out to me I'm focusing on the wrong things. I want to know what you Sej mains think she could use, assuming she will get changes.

Do not mess him up like you did Vel. He's fine, he could just use some minor number tweaks depending on what the rest of the cast has.

Even though I am heavily biased, we can all agree Shen needs another change, despite being a Warden. He isn't fulfilling his fantasy in a healthy way and his tools are so overpowered in the right hands that they are forced to have atrociously low impact except in a perfect world. And for fuck's sake his E is still buggy and is stupidly narrow for the huge cost of just casting the damn thing. Not to mention the timing of his abilities do not match each other. Could use some outright tweaks, but outright number buffs might be dangerous.

Rework or remove this item. Hardly any tanks build it and Ezreal has become the most annoying piece of shit using it.

Re-emphasize this item's defensive nature and repurpose it as an item for tanks/bruisers who rely on autos and get kited. I'm sick of people like Yasuo building this and becoming an uninteractive mess of tanky, lifestealing destruction.

Further explore items like Randuin's and make ways to negate crit in more items without making it too stat-checky.

This item is only good against and on a few champions early and heavily falls off. Thornmail needs to become impactful.

is too impactful as a first purchase on most tanks. It's crowding out most itemization, may need to be looked at.

Buff this item or rework it. It sucks, it doesn't feel impactful, and is better on some tanks than others, yet is built by none of them. Doran's shield sucks and is a bigger waste of gold than building Rabadon's Deathcap on Darius.

A long shot, could do something with this item somehow. Turrets are kind of obsolete right now.

We also need more CDR options, more magic resist options, and possibly more defense against %HP damage. The only way for tanks to be impactful right now is their burst damage. After the update (if Riot does it right) we'll see more wet noodle fights, less tank deletion (going both ways), a better laning phase for tanks, and in general more survivability in this FPS meta where you run in, die instantly, and wait to respawn while being rude to your teammates.

Oh, and a tank item that inflicts grievous wounds would be nice. Maybe something with an active.
