Oh look all boots are useless and only one is good? what the best idea to balance it?
Nerf 
because when you have 5 useless boots the best solution is to have 6 useless boots!!
When you increase the cost on all boots but nerf the stats what you expect to happen riot? to people buy tenacity boots? 20% tenacity? yeah no thanks its useless
You think as a jungler i would give 1100 for 
no thanks
So STOP nerfing items riot people use that items because the REST OF THEM are useless
Is like DPM sunfire and omen are useless and riot is all like "well we are not gonna give omen a better critical strike reduction or the 70 armor back we are gonna nerf DPM"
Seriously?
