[POE2] New Powerful Cooldown Support Gems to incentivize more attack skills.

A possible way to make players use more than one attack skill in POE2 would be to add a whole new kind of support gems that modify skills in a major way while adding a cooldown to the skill.

Example:
Bleed Support
Supported skills always inflict bleed.
Increased chance to bleed instead increases the damage of any inflicted bleeds.
Supported skills have an 8 second cooldown.

With a whole set of these for any other ailments like freeze, burn etc.

Can be combined with other support gems to give a big bleed effect on single target, Freeze on a big pack or whatever else.

Big bonus of this is it interacts very well with all the existing skill gems and support gems and doesn't require the addition of many new skills to fit this new niche.

Other example effects: Suck in nearby enemies towards the enemy hit.

I've been hoping they'd do something like that with movement skills. Make a leap slam or dash SUPPORT for strike skills. Let the movement part have its cooldown, but let you do the strike itself while the movement part is on cooldown.
