I think Rageblade would be much healthier without the AD/AP ratios holding it back.
Removing those ratios would allow the attack speed and passive to be buffed.
I was thinking it could have 30% base attack speed and 7.5% bonus attack speed per stack, with the total stacks required to activate Guinsoo;s Rage reduced to 4 from 6, granting a total of 60% attack speed. (if 60% is too much, 25% base+6.25% per stack=50% total.)
slightly less power in extended fights but imo a fair trade for the quicker Rage passive which is the the whole point of the item.
its hard enough to stick to a target long enough to smack them 6 times, thats usually what someone hopes to do before the fight ends/they die or have to retreat, not what they hope to do before their power turns on
price may change accordingly.
