A Burst mage/Crit Rework Idea, Plz no troll

So I have been taking some time, thinking of this, what if the current unfun crit system was reworked? but not just reworked, it was reworked to include burst mages, allowing for proper scaling of them (rather then just if they get ahead they kill everything, if their behind they do nothing), but lets get started on the key points Firstly, Crits will now do 0% extra damage at level 1, why? because crits now ignore 50% of bonus armor and MR, what does this mean, it means burst mages will be harder to mitigate by just stacking MR, (Basically, no more maw zeds dominating burst mages without counterplay, or vlads stacking visage and health to bascially be immune to mages), Now your probably looking at me like I'm a retard, but heres the thing, from now on abilities Can Crit, but not in the same way auto attacks can crit, So a few new items would be added

Blasting Ring - 1000 gold Builds from nothing Unique Active - Unrestrained power: Your next spell or ability WILL critically strike (30 sec CD) Unique Passive: 10% Increased critical damage

Enchanted Codex - 900 gold Builds from Amplifying tome 30 Ability Power Unique Passive: 10% increased Critical damage

Deathfire Grasp - 3500 gold - Builds from Needlessly Large Rod, Blasting Ring, Fiendish Codex 100 Ability Power 20% Cooldown Reduction Unique Active - Unrestrained power: Your next 2 spells or abilities WILL critically strike (20 Sec CD) Kills refund 15 Sec from this Cooldown Unique Passive - Deathly Touch: 40% Increased critical damage

Sword of the Divine - 3650 gold - Builds from BF Sword, Blasting Ring, Caulfield's Warhammer 80 Attack Damage 10% Cooldown Reduction Unique Active - Unrestrained power: Your next 2 spells or abilities WILL critically strike (20 Sec CD) Kills refund 15 Sec from this Cooldown Unique Passive - Deathly Touch: 40% Increased critical damage

Along with these New items (or rather 2 new items and 2 returning items), Several older items would see reworks aswell to accommodate the changes to Crit, Including a rework to an item we all know (not gonna list all the changes done to items tonight because I'm tired asf)

Mejai's Soulstealer - 3200 gold - Builds from Blasting Wand, Enchanted Codex 80 Ability Power Unique Passive - Siphon Of Souls: Reduces Remaining time on basic ability Cooldowns by 50% upon Takedown Unique Passive: 35% Increased critical damage

Now your probably asking, why rework mejai's? well its just a badly designed item.....all it does is allow for a massive un-needed snowball gap which would get further exploited by stacking it with Rabadons and AP crit items, and since burst mages will be able to focus on crit rather then needing so much Raw AP, They wont need mejai's anymore Now Critical Chance would remain but champs like Tryndamere/Yasuo will no longer get overwhelming so fast with their bonus crit chance as they would need to stack crit damage items, Additionally champs could now be given bons crit damage on abilites (fiora E) that would scale with the extra crit damage gained aswell Give me your thoughts on this idea, and if you really need to, call me stupid for wanting to rework crit lol, seriously though, I wanna know what people think
