Flash Tiny Change
Besides for some rewording on things that affect Flash like Distortion Enchantment (and possibly an additional text for the summoner spell CDR mastery), Flash will be exactly the same. The idea here is that Flash will be removed as a Summoner Spell, to open up spell diversity, but still have access to everyone since everyone uses Flash every game anyways.
The idea is: Flash will be a free (you must purchase it from the shop) active item. This item will not consume an item slot since it can combine with any fully completed item that does not have an active to it already (you click and drag the item into an item like you are moving it to another slot to combine it with that full tier item; to move the Flash item to another slot without combining it that an item on its final tier already is in you move that final tier item instead of moving the Flash item).
The Flash item can be combined with doran items and tier 2 boots with or without an enchantment.
This idea is to keep Flash in the game while bringing Summoner Spell diversity, otherwise Flash should be removed from the game because it is the overally dominant option.
