Kindred's attack range and her passive

Her attack range is rather on the low side (500). Her passive at 4 stacks gives her 75 bonus range, however, playing the mini game may be rather risky, so her potential is severely limited until she hits 4 stacks. This means, if she's behind, she's going to stay behind due to her need for marks.

Would it be better to shift some of that over reliance from her passive to her attack range like 525 with 4 stacks giving bonus 50 range or 550 with 4 (and on) stacks giving bonus 25 range?

Because at the moment, her winrate is rather terrible and I don't feel her buffs on the PBE is going to make much of a difference.

I feel like there is too much emphasis on the marks rather than giving her an extra perk (like Shyvana's passive), which means less power in her 4 abilities. Seeing that she doesn't get her bonus damage from her marks anymore, it seems her damage output has dropped significantly as well, but she still remains pretty squishy.
