This one is really good. Components, build cost, passive. Might need a review. Not too much worried about that item to be honest.
This one has recieved so many changes and nerfs, not even because of melee champions but ranged ones. This one i do believe it might need a small buff. It used to give 20 ad, but the cost was higher of course.
This one is the current busted item among the AD tier that it belongs to. And i agree with you that needs to be pinned to discusion at some point. I do not believe that its a fair item, and probably part of the reason why Wukong liked it and got nerfed recently.
Even this one, cannot measure itself with Serrated Dirk, which is amusing if you think about it. I Mention this one because you forgot to mention it. And used to be part of the recipe for
. Until it got changed due to certain abusers -cough-
.
Now, about tiamat.
tiamat has a really good cost for all that it offers, and there is only 1 champion among the pool that takes full advantage of the item cost effective wise, and as far as i know, this hasn't been changed to this day
. But that's another topic. Not complaining, just trivia info.
I think its gonna impact certain junglers, and its gonna hit also non Trinity users. I really hope the nerf its just gold cost and not damage. But only time will tell.
