Add grab mechanic and/or adjust push and throw on targets.

[Marquis de Salt]

Adding a mechanic is probably more complicated than it looks, but it opens up alot of interesting plays.

In 5e, grapple mechanic sets the target speed to zero. From there, someone can drag and throw, relative to weight with size factor. But just holding someone still makes spells like cloud of daggers or zone of silence alot better. It's just another way to control the battlefield.

Aside from that, adjusting push mechanic to relative should be easy to add. For the moment, I get the feeling it does not factor it into it's mechanic, but just weight. It makes it sorta lackluster.
