New summoner spell and possible types?

so there are a few ones to say as of now that could have elemental properties. why not toss in a few items to give those spells different stats too? flash could do some damage, ignite could heal a bit, heal could give ms to teammates, remember old masteries doing stuff similar to changing the summoner spells up? also just throwing this out there... an invincible button? like zonyas just moving at the same time. the poro dash could work on walls too. a new charging summoner spell while walking to give a small boost based on your movement stacks. having caps, but low cd. remember promote- why not have a summonerspell minion (that spawns on cast wherever clicked and does what you click it to for a time limit. like a functional voidling). making it so barrier could be like a charging spell. a healing area for fast regen (overall doing more than heal but you have to remain in circle for full result). Remember old fortify doing a invincible turret for like 5 seconds doing aoe and passive extra damage to minions on the champ or ignite doing an extra 10/10 ad/ap or heal giving health per level? bring some of those masteries back- like a bigger list of previous masteries that could be used in todays meta that wont be broken or useless. CHANGE IT UP AGAIN RITO PLZ. this meta is boringasfuk
