What is your first impression on the midseason patch?

Several changes hit live and it's time to overreact! So what do you think is broken OP or useless af? It's obviously too early to actually draw some conclusions but I'm interested in your first impression. Don't downvote others due to disagreeing, first impressions are prone to mistakes.

My first impression:

• Sejuani: disgustingly OP. So much stickyness, CC and tons of damage. Demolishes tanks, squieshies and everything without dying

• Zac: pretty good, not too strong. His ultimate seems super good, but I think nobody payed attention so it might not be that strong.

• Maokai: weak. His ultimate is sort of underwhelming, his 1v1 is much weaker due to W and R changes and overall.. Ehh.

• Guardians Angel: Can't really say much, but I just supported a Caitlyn who rushed it first item. NOT A GOOD IDEA PLS DONT DO THIS TO ME

• ArPen vs Armor: felt like I did no damage to tanks. IMO the BC changes were too much, but the LW ones were more than fine. Make it melee only?

• Lifesteal itemization: decent, sort of makes up for ArPen nerfs. It's hard to hurt tanks, but they can't hurt you either (aside from Seju, fuck Seju)

• Support items: gimmicky. But that's fine because it feels somewhat rewarding despite not being broken

• Herald: saw it twice, took whatever was left from 1 turret and that was that. Maybe something from the 2nd aswell? Seems underwhelming, but people can't use it properly so far, so I guess it will get better
