How to introduce more counterplay and decision making to Kalista's kit. (A creative nerf)

Reduce the range in which you can activate Rend and the range before stacks fall off. Think about it. If she's backing off the whole time building up rend stacks, then you also move away from her and the stacks fall off. This introduces both counter-play as you can simply re-engage once the stacks have fallen off (which is the bulk of her damage before she gets a few items under her belt), and decision making as she would have to dash toward marked targets or stand still/dash sideways to activate rend.

So basically, you would have 2 ranges on Rend - the Range before stacks fall off marked enemies (lets say 750/800), and the range Kalista has to be in to Activate Rend (lets say somewhere between her AA range of 550 to 650/700).

Another, slightly more obvious angle, would be to reduce the number of dashes she can perform within a second to discourage stacking AS (as is the case currently with the ridiculous Greaves, BotRK, Hurricane build) and cap it more around the attack speed of Greaves and PD.

idk. Food for thought.
