Who does NOT take Flash?
That mains a lane where they usually would, which I think is every lane. '0'

It's safe to say almost every jungler takes
, but Shaco typically goes

Ming. Ming does not take Flash.
Some that I can think of off the top of my head (keep in mind that it's largely personal preference and not everyone uses the same summoner spells on a champion):







[If you haven't noticed, Hecarim has a lot of options :P]
Honestly, Flash is a better "OH S***!!!" spell, but Ghost is definitely a viable alternative for many champions.

I don't tend to take Flash that frequently. Sure, it's a powerful summoner spell, but there are a lot of good options out there.
If I'm playing on the Rift, I only take Flash if I'm on a champion that desperately needs to be able to reposition quickly.
Vlad mid or top I take tele and heal
i prefer ghost over flash on most tanky dps-champs. Most easy firstblood with darius lvl 1, start W, walk up to your opponent(melee) once he wants to last his a ranged minion, aa, reset it with W, pop ghost and keep hitting him(don't forget to use animation cancleing to constantly stick at him) even if he uses flash, you wil catch up ~1-2 sec later with ghost, and thx to noxian might+bleed, you can just train down anyone.
ghost allows to cover far more ground than flash total, with lower cd. So unless you have a bursty or cc champ that wants flash for supprise butsex, or a squishy that needs to get out off danger asap, ghost actually is really strong.
Faker doesn't. Faker doesn't even take any summoners.
i never take this summoner dont like it not interesant to pick this and friend my firend call me troll pff [slayer-jinx-unamused]
only people i know didnt regularly take flash are top laners and shaco junglers. now its just shaco junglers
(top lane)
If you're feeling confident, some other top laners that can go without it:

Basically, I'm saying most top laners with a dash or MS can forgo Flash in exchange for a combat spell. It can turn an even or losing lane in your favor. If the enemy jungler comes top, if your teammates are decent, particularly your own jungler, it means free dragon buffs.
I'm sure you could make a case for Urgot. Flash is always good for when you are trapped, but to get away or to pursue, ghost could get you more bang for your buck
I sometimes don't take flash on Karma.
