So how to understand this?

Gypsylord postet on twitter:

End result? Kindred becomes an actually squishy champion (similar to other ADC's) which allows burst and melee focused characters to take advantage of her easier in the early game.

Soooo Kindred is supposed to be strongest in early dueling but they want her to lose a lot of her duels from now on if the enemy actually attacks her?

Thats what this explanation seems to me.

How to get stacks then and be relevant in any later phase in the game?
