Skill gems slight alterations uniques or support gems

Examples: let say you use ice of orbs instead of shooting forward you get a unique or support gem that makes it go in a circle around you or the rob stays in places but acts like a turrets just more changes to skills, inculding what's there. not only that but also combos with another skill gems, we need more build variety and I believe this is what's lacking is uniques or supports that change or alter the skills we use making builds feel different from one another we have some things but we need alot more. We have some copy and paste skill in other classes like lighting archer feels like a lighting sorceress.we need more visual changes.
