It doesn't bother me. However, I would love to see characters deviate a bit more from each other. I'd like to see items with more synergy per character too.
Stuff like Ravenous Hydra for Melee and Hurricane for Ranged are actually pretty good ideas in small amounts. As long as we don't end up with ADCs using 4-5 range-specialized items while people who don't adopt end up "noob-trapped".
There are a lot of new things people can play with in any role, its just that the items that the standardized item builds are tried and true and can work with pretty much any situation thrown at them. There's definitely a lot of niche items you can throw into your build, but people don't like to deviate much from what they know will get them through just fine if not optimally.
