@Riot armor and Magic resist diversity for season 5?

So im confused i just read the preseason 2015 forging a diverse armory and was quite shocked when i read this.

"To smooth this out, we’re changing Chain Vest to build out of Cloth Armor and removed Negatron Cloak from the game (replacing it with Null Magic Mantles earlier in item build paths). This makes the “I need Armor NOW” case much cleaner, no matter what final item you’re aiming for with minimal loss of depth in the decision making."

It doesn't make sense you're making it so cloth builds into chainvest to add diversity but are removing negatron cloak instead of just doing the same thing. you are effectivly reducing diversity by doing this if i want a decent bit of magic resist i have to buy 2 null magic mantles or finish my magic resist item i can no longer sit on a negatron cloak for 15-20 minutes for the solid MR then finish the build later.

unless i am misunderstanding what you mean by "removed negatron cloak" i don't seem to understand. if you are removing the cloak all i can gather from this is that you guys thought it was a great idea got done with the armor bit but was like "oh shit we are running out of time lets make up some bullshit for the MR section so we can get this shit out the door." is what im getting from it.

so please rito, elaborate.
