@Riot, people are not mad at the mage items idea in general.
They are mad at the direction you guys want to take mages.
1- Less AP overall
Patch 5.13 already did a good job on lowering the overall available AP. We don't need another AP general nerf. Because yes the 5.13 patch, that was supposed to make builds more clearer between damage and utility and blablabla, was just an overall nerf to AP because of the destruction of the 120 AP tier that was merely compensated by a 5% AP buff on rabadon. And now you want to make Zhonya a worse item.
2- Removal of what is already good.
Catalyst now gives you HP when you get hit instead of rewarding you for staying in lane and leveling. Who want's to get hit to get sustain? It's kind off useless.
Rod of age, one of the only viable AP item nowaday is getting gutted because it's over picked. It's not picked because it's strong, it's picked because it's just better than the other items.
Athenes, the core item of long range poke mages and mages that need a lot of mana sustain, got destroyed and is now only usefull on supports. And by usefull i mean ok because the mana regen is totally gone.
3- addition of items that don't fit what players want for immobile mages or the game in general.
I'm talking here about the dash belt. Giving mobility to everyone is probably one of the worst idea to counter immobility as a weakness. And even if it worked, tanks will make a pleasure to show how ridiculous this item can be by spamming it.
I play mostly mages, and I'd favorise raw AP and SOME usefull passives/actives instead of 371209371938717092 possibilites of items that give mediocre stats and different actives.
Mages, are WEAK. those changes should increase their stats, not just make what is bad even worse and then adding a band-aid on the open wound.
