More skills related to positioning

Hi, with the emphasis on positioning in this game, I thought it'd be good to have more skills and features related to positioning.
Like a defensive skill that blocks attacks directed at yourself and people adjacent and behind you.
A melee attack that causes you change location, "slashing" through enemies.
Spells that suck a group of people together and slows them.
Spells that send enemies flying or blows a group apart.
More buffs and skills that work only when people are standing side by side or adjacent.
Melee attacks and spells that attack in a cone in front of you.
Defensive skill that increases your collision radius, making it more difficult to move past you.
