Summoner Spell Flash changes. (logical perspective)

Summoner Spell Flash in theory the champ disappears and reappears in desired location should be unable to be a target in that duration which is I'm guessing .25 seconds as well as evading any on-target spell that is being casted on the target because in theory the spell no longer has (in-range) mark on the target unless it's a tracking missile which no champion has ( Corki comes close) . So for example if brand uses his ult and his fireball, which is a locked-in spell, is halfway and the target flashes out of the spell's range it is logical that the fireball has no where to go or does not know where else to go since the target that it was locked onto isn't in its range anymore. Another circumstance would be Syndra's ult, which I completely like its raw power but in fact a little unrealistic because like it says in the description of the spell she should actually channel her energy for maybe a second before unleashing her wrath with her awesome balls. Kind of like the Morgana ult that the enemies have to stay in range for her stun to activate, same thing should apply to Syndra. Which can be a moving channeling ultimate gathering any of her spheres that are in the battleground making maybe a super saiyan scream while charging up and if the target locked on is still in range then she can deal all that massive damage because she deserves it, maintaining her target at the ults range. Continuing my point in the flash topic if the target flashes out of Syndra's ult before she can channel her energy to the target then the ultimate is wasted because there is no locked target in-range. Logicical right? Along the same lines, turrets should not be able to track the enemy down like a heat tracking missile when you flash out of range. It really does not make sense at all when you "disappear" and magically the turret blast still follows you like it knows you went to another dimension and will come back so it waits and then tracks the you down to deal damage (potentially kill you). Even though Flash is still the most essential summoner spell it should do more. I believe this change will make all players very happy and I would love to work for riot and discuss all my ideas with the board to make this game the best it can be.
