"You don't HAVE to pick flash." Well, most people always take it.

Personally, I think Summoner Spells are a problem, it breaks champion balance. Example : I am a squishy ADC with tons of damage but that can't escape a gank, normally, you would have to deal with it, but you just take ghost/flash and magically you can escape, thus removing the weakness that balanced your tons of damages.
