Yeah they were gonna scrap it but didn't. Guardian items are crap.
They should NOT be in every starting item set.
I haven't gotten used to the gold flow changes but the increased gold for kills and the minions starting at high gold makes it even more important to snipe last hits.
The passive gold also makes turtleing when you're comp can't fight until 6 impossible; but it's a strategy you have to use sometimes depending on the champs you're dealt.
In this case you now lose in champ select. I haven't seen a comeback yet.
I don't think the SS cooldown is a big deal.
What is huge is the removal of all the ms engage items from the map, making snowball mandatory now for some.
Double edged sword is a big confounding culprit this patch as well, I don't know what that's doing to the map either.
I haven't faced a Teemo/Shaco as of yet, but how are we to kill the traps now?
Oracles just reveals them in red untarget-able status.
The widening of the area near the base now makes it harder for the defending team to set stuff up; before we had a choke-point to get them and make a comeback.
Now you're probably better off fighting on the bridge without your turrets, to be brutally honest.
If they increased the nexus turret ranges and pushed them slightly forward it'd be a start.
There's other stuff, but I don't want to give a bigger wall of text :P
Maybe I'll put it all in one post; gonna take me a bit though...
