No. Just no.
However!
I would be interested in seeing some "Legendary" items in the shop. Some can be enormously expensive (to make those really long games interesting) or perhaps have requirements to unlock the ability to purchase them (i.e. have over x cs, get a pentakill, destroy x objectives) some can also be built out of current items like maybe make a SUPER IE/BT/BotRK/TF etc... and then just make them really hard to get so like even getting one in a game is difficult but if you manage to pull off the requirement(s) or actually invest enough gold you get this epic item that isn't seen often.
Like imagine an item like this:
ULTIMATE TRINITY FORCE
Builds from:
+
+
+ 1337 Gold
Special Build Requirement: Must have blue, red, and baron buff to purchase. (All buffs are consumed once purchased.)
+40 Attack Damage
+80 Ability Power
+400 Health
+250 Mana
+50% Attack Speed
+35% Critical Strike Chance
+10% Movement Speed
+20% Cooldown Reduction
UNIQUE Passive: Champion can move through units.
UNIQUE Passive: Dealing damage to an enemy champion cleaves them reducing their _Armor and Magic Resistance _by 5% for 6 seconds (stacks up to 6 times, up to 30%)
UNIQUE Passive - Spellblade: After using an ability the next basic attack deals bonus _true damage _equal to 200% base attack damage on-hit. (1.5 second cooldown)
UNIQUE Passive - Rage: Dealing damage grants 20 movement speed for 2 seconds. Assists on cleaved enemy champions or kills on any unit grant 60 movement speed for 2 seconds instead. This movement speed is halved for ranged champions.
Just a random example, but this gives you some kind of an idea of what I am talking about.
