I Don't Think the Kalista Buffs will do That Much

As the title says, I don't think the Kalista buffs will be that huge. In case you don't know, Kalista has these buffs on the PBE: her E will now stack when it's on cooldown and her E will have its full mana cost refunded for killing 1 minion. Now, why I don't think that this will do all that much is because all they do is buff her lane phase. Right now, her passive, Martial Poise, allows her to dash in a targeted direction on basic attack and cast of her Q, however, her basic attacks cannot be cancelled (which I think is actually a good thing - I often miss kills/cs because I accidentally canceled my basic attack), her basic attacks deal 90% of her AD, and her basic attacks don't deal damage or apply Rend stacks if she loses vision of the target during the animation. Her basic attacks only dealing 90% of her AD instead on 100% like any other champion means that her late game scaling is pretty weak, however Rend enables her early game to be very powerful. Now, why I think the buffs won't do much is because she's already incredibly strong early game, yet falls off incredibly hard late, and all the buffs seem to serve to do is make her early game even more powerful, while leaving her late game incredibly weak. Her only real scaling is her ability to engage teamfights by throwing her support in (which is certainly not something to be underestimated) and the Rend damage (again, not something to be underestimated), but while she's stacking up Rend, she does almost no damage, and I don't think that these buffs will make that any better.
