I Feel We Need An Itemization Overhaul
I understand a lot of people are not going to agree with me about this, that's perfectly fine, but one of the core things about League that hasn't properly been looked at as a whole, is Itemization. During Pre-Season for 2019, I believe Riot needs to re-evaluate every finished item in the game, possibly even starting items. When this happens I feel items need split between Melee-Ranged-Neutral in a much heavier way than they are now for offense items with defense items remaining available to all champions, possibly a few defense items being melee only so ranged champions can't abuse them.
There would need to be a good number of each of the 3 types (Melee-Ranged-Neutral) to not make it seem like they're being restricted by the amount of options, but not too many where it seems like one type feels like its being favored between Melee and Ranged. Neutral items would be available to everyone, so that will end up with the most items.
Why would I want this kind of system to happen? It's very simple, abuse cases. There are way too many times in this game's history that other classes have heavily abused items that were buffed for another class to feel good (Duskblade for assassins, Spellthief for AP supports, Targon's for supports, etc), last season being the biggest number of abuse cases to date.
By making things split between the 3 types much heavier will allow for better tuning of items to the point that the game's balance might actually get back on track after so long. When 1 class abuses another's items, that's when things get thrown off and the game's fun levels drop. There would have to be a balance between AD and AP items in the 3 classes of course, due to the number of ranged and melee champions between AD and AP builders which will be the more challenging part, making sure both physical and magical damage have plenty of each type.
This also allows for easier tuning when one attacking range gets out of hand without fully disrupting the other's itemization. There will always be abuse cases, but the weight of 2017's abuse cases was too far out of hand so I feel that this system needs to, at the very least, be internally tested to see if it will be viable for the game's health.
Thank you for your time.
