[Suggestion]: Targeting champions and targeting in general

I can't tell you how supremely frustrating it is when you're playing a support champ and you try to use a support spell on an ally, but it winds up hitting a minion instead.

Now, i can understand that there are certain instances in which you would want to target a minion (i.e. hitting an enemy minion, etc.), but what, may i ask, is the point of casting Soraka's E (infuse) on an allied minion?

I have no doubt that someone will try to make an argument about it being the player's responsibility to target properly, but when the game is going on, it's harder to hit one's target just like that. Therefore, I'm proposing that certain abilities, primarily those that are intended to heal allied champions, be made to target only allied champions and not minions.

Along those same lines, since i started playing a couple years ago, i've noticed that the targeting system isn't as good as it could be. Now, this could be due to lag and other extraneous factors, but a number of times my game has been thrown off when i try to target someone, but my ability doesn't go off, even if i know that they're in range of the spell etc.

I would love to hear other thoughts on this.
