Possible Summoner Spell
Read a thread about how League could use a new summoner spell. (http://boards.na.leagueoflegends.com/en/c/gameplay-balance/pgmLyBZP-will-there-be-another-summoner-spell) And it gave me these ideas.
New Summoner Spell: Repulse
Function: Pushes all enemies within 250 units (Half of Lucian's attack range for those who need an estimate) 500 units away from the caster.
New Summoner Spell: Gravity
Function: Pulls all enemies within 500 250 units to the caster.
Explanation: These are just ideas and may not be balanced, what do you think? Repulse could be used by carry roles to interrupt assassin burst or counter an engage. Gravity could be used by tanks to peel for carries or to set up aoe or line damage combos for their team.
