REMAKE RAGEBLADE
There are still a couple of items that are really niche picks or simply offer stats that are inferior to similar items. One such item is Guinsoo's Rageblade. Who is supposed to use this item? Kayle, Jax, Teemo? Kayle and Teemo are far better off getting Nashor's and then building straight AP. Jax can't trade a Tri or BOTRK/Gunblade for it because they offer similar stats and he needs the reliable sustain / stickability. The problem with Rageblade is that it offers no utility and simply isn't strong enough as an offensive item.
I think this can be solved a number of ways, namely giving it some mobility or reliable defensive utility. Here's my proposal:
New Guinsoo's Rageblade (Cost = 2900):
Pickaxe = 875
Dagger = 450
Blasting Wand = 850
- Recipe Cost = 725
Item Stats: 25 Attack Damage, 50 Ability Power, 30% attack speed
Basic attacks and dealing spell damage grants +2 attack damage and +4 ability power for 5 seconds. Stacks up to 10 times, granting a total of +20 attack damage and 40 ability power.
UNIQUE ENRAGED: On max stacks, grants 30 movement speed, 5% lifesteal & 15% spellvamp.
I think this would make it easier to stack in combat because of the innate attack speed, but change the stacking rule from "using ability" to "dealing spell damage" so that it cannot be abused into perma stacked mode by nidalee etc. the reduced timer would also make it harder to abuse and keep stacked. This would make it into a great mid game item for any champ who uses the stats and can sustain long combat either by duelling or by poking in lane.
It can compare to items like Tri or Gunblade, but does require long combat to achieve it's potential. The 5 second timer would allow more counter play to the item. But when stacked, it gives great stats that makes it behave more like a top-tier item.
