Here are some of my first thoughts; Overall I rate this a 7 out of 10 patch.
I hope the talon crowform change, doesnt make it through, same as this nonesenseicall change to circlets. Tranquillity nerf is probably not enough, since it is the only REAL out of combat ultimate. The nerf to hardend skin is literally what I wanted to see all years, but it might still be not enough.
anyway, speaking of items again; leave the circlets as it is, its a good item and thats it. nobody needs this nonesense “Oh yeah I could to this hehe-stats trick mid fight” since you have mostly much more important things to do, but I can understand the argumentation of players, saying, it was too strong, since a circlet gives basically a levelup in terms of stats. so level 3 hero with 3 circlets becomes roughly a level 5-6 hero, statswise, but anyway, I think the change with the toggle is kinda nonesense.
Make it like this: circlets stay the same, ring +3 is good, gauntled is good same as mantle and the new’ish cloak. now if gloves of haste, get the true 15% attackspeed, instead of the 11% that it actually provides, wand of manastealing is overtuned imo now, so 60 points of mana stolen might be enough. periapt of vitality is probably the worst of all drops by now, so removing it completly might be the correct idea (for 1on1s), since if you compare it with all the other items, especially with ring of regen, it kinda fells of heavly. maybe someday pendanty of mana and energy need a further nerf, but imo with what I wrote down, we are close to perfection, in terms of item drops.
