Stormrazor is a bit useful in late game +maybe more crit items?

So Stormrazor is back on the pbe and got some good changes. First thing is they added so you need other items to get the bast out of it and that is nice but i feel like it is less useful in late game because it's crit damage is increased by your crit chance so you won't deal 140% damage crit with 100% crit chance but then it made it's real use in late game to have +70 AD ,30% attack speed and 10% movement speed after your first crit every 3-0.38 seconds(base on attack speed) so why not give it the ability to deal more then 200% crit damage late game maybe something like this?

STATS: +70 attack damage +30% attack speed

UNIQUE PASSIVE: If you haven't attacked for 3 - 0.38 (based on bonus attack speed) seconds, gain STORM'S EDGE.

STORM'S EDGE: Your next basic attack critically strikes for 150% - 250% (based on critical strike chance) damage and grants 10% bonus movement speed for 2 second. (range champion max critical strike damage is 225%)

this help it late game but is still useful in early game.

and i got an idea to this item:

Recipe: (400g) + (1500g) + (400g) + 350g = 2650g

Stats: +30 attack damage +20% critical chance +10% life steal

UNIQUE PASSIVE: critical strikes will reveal the target for 3 seconds and heal you for 10% of the damage dealt.

UNIQUE ACTIVE: deal 10% of the targets health as physical damage, slow the target champion hit by 70% for 1 second and heal your self for half of the amount of damage. (550 range) (90 second cooldown).
