A proper change to our big OnHit and hybrid item
As mentioned in Irelia Bots post of a hybrid pen item idea, rageblade is felt to be part of the problem with both on hit and hybrid itemization. It really shouldn't be trying to be both.For most of its life it was a more mid cost hybrid item then it was buffed quite a bit with +ad stacking, increased attack speed stacking, and a max stack passive that turned everyone into kayle around the same time that sated devourer came into existence making the 2 items alone extremely cost efficient with each other, too much so. If you were comparing the possible 2 item damage spikes for the dominant carry champs: APC with void staff + deathcap vs ADC with upgraded zeal item + IE vs hybrid carries with rageblade + devourer; the hybrids were spiking objectively hardest and most definitely sooner than any of the other carry types. Rageblades dominant power of this point could have been greatly reduced simply by removing the on hit.
Then there is the on hits, every type riot has put out an on hit that would look to be the strongest of the general on hit items it was many times so strong that it frankly could be the sole damage item for the on hit and was limited by trying to intend it to be a late game item but again were so strong that they could scale on their own into the late game with no other complementary items like the 2 item powerspike example above. Crit and on hit based carries have always been having the tug of war on which group has the biggest epeen, with the swings largely happening from the balance changes to the on hits, either so strong that you really only need attack speed but other on hits further spike the damage or on hits will simply not be strong enough warrant stacking.
Both options are possible to make in a way so that they scale best with the items that would be assumes would be purchased on each separate group.
GUINSOO'S RAGEBLADE
+ 
+ 1000 (3000 total)
+30 Attack Damage
+40 Ability Power
+20% Cooldown Reduction
+400 mana
UNIQUE passive: On basic attacks grain +4 Attack Damage, and +6 Ability Power for 8 seconds (stacks up to 3 times), and every 3 attack grants a stack of Guinsoo's Rage(Up to 4 stacks).
Guinsoo's Rage: Next ability cast gains bonus AP equal to 15% total AD and gains bonus AD equal to 30% AP restoring 20% missing mana upon dealing damage
The biggest thing that had to go was the synergy with general on hits so on top on any on hit effect having to go attack speed needed to go to. I know maybe hybrid AA champs may cry at this but they likely already have an attack speed steroid in their kit and with many of their abilities having lower general base cooldowns they will have more opportunity to cast the abilities in a more of a weaving fashion of AA's and abilities considering many of these champs are sheen users that shouldn't be a big change to them overall, instead of boosted sheen auto's you will have boosted rageblade abilites. For the hybrid casters/assassins the held stacks that can be easy to build up with proper planning will allow for full q+w+e+r skill rotations with boosted damage. Overall weaker stats on base level and max stacks, but much faster overall stacking and a passive that should be okay with the item on its own but best with complementing damage items and be better fit a wider pool of hybrid scaling champs. With gunblade being the only other pure hybrid item, every other item after either one or both of these items together will be up to what will fit on the hybrid champ who should have even better item flexibility after this rageblade.
[ON HIT ITEM] - I feel like this is what zehpyr could make a return as
+ 
+ 
+ 800 (3300 total)
+30% Attack speed
+40 Armor
+150% base health regen
+5% movement speed
Passive: All basic attacks now instead deal 100% total AD as on hit. Life steal still applies to this damage but critical strikes don't.
UNIQUE Passive: All on hit damage is increased by 14%(+2% per level) of your total bonus attack speed percent.
UNIQUE Passive - Point Runner: Builds up to 20% movement speed over 2 seconds while near turrets, fallen turrets, and void gates.
This one having a passive geared to increasing on hit damage as you continue to gain attack speed, through levels, passives/skills, and items. So for example max level assuming the champion has 60% bonus attack speed then all their on hits will be dealing 30% more damage including their auto's since they will be an on hit also. Not only is the item meant to be especially geared towards on hit champs it is tuned to discourage potential abuse cases of crit bases AA champs, you can only have one or the other. And will be having the best synergies with on hit champs that have built in on hit damage on top of regularly building it from items also. Because of the limitation of the scaling from both levels and attack speed+on hit it shouldn't be so much of a one item wonder that previous problem on hit items were, you will only have the best possible damage buy further building up your main damage source.
