Make the "Inevitable Critical" support gem do what it says

The gem is useless due to how little the bonus is. It adds base crit chance which is derived from items and Struck Through node.
On low crit% builds it merely adds ~5% crit chance after 4 seconds. More or less higher crit chance builds simply don't need this stupid gem over damage bonus ones because in best case scenario and pretty late into the game it will add ~14% crit chance after 4 seconds (staff builds).

I'm asking devs to make the gem do what it says: make it a guarantee crit after 4 seconds.

It will create many interesting setups and leveling methods without harming overall balance.

Thank you.
