I have little to no problem with the new items, but, there is one thing that bothers me greatly.

You see... Let's take Kunkka for example. One of his abilities is called Tidebringer - in fact, let me just show you:

"A lost Claddish soul inhabits Kunkka's trusty Tidebringer, empowering it to destroy demons of the Cataract."

It strongly suggests that Tidebringer is the name of his sword - his default sword which is also shown on the icon - but the problem is that he has as much as 3 more weapons. As of me, it would have been a great addition if skills like this one (or, for instance, Tidehunter's Anchor Smash) would change their icons and spell lore if a certain item is equipped.
