Can we have new summoner spells?

It's been a while since we've seen new summoner spells in the game. In most cases, we get flash + another summonner spell based on your role

• Ignite for most mid champions
• Heal for adc
• Exhaust, ignite for support
• Teleport for top laners
• Smite for junglers

Ghost, barrier and Cleanse for whatever unusual matchups.

We used to have more summoner spells back then, but they where simply removed and moved to items

• Promote (Zzrot portal and the once used banner of command)
• Rally (really old)
• Revive (Basically only used by Karthus)
• Stifle (That spell would silence target and even purge them)
• Surge (Somehow reworked into guinsoo)

It would be nice to see something new in gameplay. I got few suggestions to start off with, but I think it could be a nice addition for the current gameplay.

• Something that would increase Attack range / Cast range for the next X spells. Ideal for mages and marksmen instead of taking Ignite, heal

• Something that would root/knockup/bind the a target in place or silence mages or Disarm adcs (It has an adaptative proprety) . Could replace ignite and increase combos (could be overpowered, but i'm just throwing off some ideas)

• An illusion spell. Just create a copy of your champion for X seconds and that deals 0 dmg. Could confuse targets

• A spell that makes you camouflaged (not stealthed) for a very brief moment

• Another variation of smite

• A purge spell (Remove ennemies buff, the opposite of cleanse)

The main idea here is not necessarily to judge those suggestions, but rather encourage people to ask for new summonner spells...
