What do you want to see? - I would like to see a force power being added, to stop people from moving for a short period of time. For example, force grip.
Why should we add it? - There are many good reasons why to add this (more than those that are bad). Firstly, in some events where Jedi are fighting Sith, the enemy keeps running away and force leaping - just to kill clones. Secondly, many actors like to use Jet packs, this would help combat this by shortly stopping the enemy and letting the troopers open fire on them. Thirdly and finally, this could be seen as only a Jedi thing but I believe it could heavily benefit the troopers aswell - like stopping escapees for the Shock to arrest, avoiding Sith from bombarding the troops, etc...
What are the advantages of having this? - Overall, it would benefit the rp experience and make some situations more interesting and interactive.
Who is it mainly for? - I think it should either be added to the skill tree or to the Council.
Links to any content - This is an example I found but doesn't have to be the exact one - anything that stops/slowd down the enemy would suffice. https://youtu.be/-JIKycHu8L0?t=136
