I think it would be interesting. It could even potentially turn into the way to change critical strike into a non-RNG based system.
For example, they could remove crit from all items, add a small AD ratio to Energized attacks, nerf their base damage and increase the rate at which attacks get energized so assassins don't abuse them, and change IE to scale autoattacks in some other way different to crit.
You're pushing two conflicting points. Do you want it to be an alternative to crit-- one where you always know when the empowered attack is gonna be in exchange for possibly lower damage than the crit option-- or a replacement?
They'd also have to change the way Randuin's works.
This line of thinking has been explored as a replacement TO crit, not an alternative playstyle. The idea of making Energized attacks "the crit" would be about adding burst from items to basic attackers, and it would most certainly be less than current crit.
But with this in mind... (Items are unchanged except where reasonable, gaining these energized focused effects) Energized: Basic attacks and abilities grant 5 stacks of energized per attack and apply all unique energized effects. (Base damage, added damage, bonus scaling, bonus effects. Damage and scaling will be overwritten by the highest value) Fleet footwork: Maximum energized stacks reduced by 20 Rapid fire cannon: Maximum energized stacks reduced by 30 Phantom dancer: Energized stacks gained increased by 5 Statikk shiv: While out of combat moving increases energized stacks by 1 per second. Runaans Hurricane: Bolts apply energized effects and generate 1 energized stack per attack Essence reaver: Energized attacks restore 10% of mana and deal an additional 1% of mana as magic damage Storm razor: Energized basic attacks and effects critically strike for 150% and grant 25% movement speed for 1 second Infinity edge: Maximum energized stacks reduced by 20. Energized effects gain 0.1 adaptive scaling Ludens echo: Energized effects apply to abilities and adds 0.25AP to energized effects. Runic echos: Energized effects apply to abilities and reduces maximum energized stacks by 50 while in the jungle.
