Iproved Charge

[Odiin]

Hello i have a question regarding the improved charge.
Is it necessary to spend points in this talent or i can skip it?
Because skipping it and don't reach the "impale" talent i can save some points and i can fill out the "armored to the teeth" and "cruelty" talents with max.
In this way more in my benefit or i should go down and fill out the "impale" box?

Thanks.
