Flash and the META

Flash has been in the META from the start and i don't see why

Flash has a cool down of 300 seconds which his exactly 5 minutes, an average unranked league game goes for just over 30 minutes meaning you can only use flash a total of 6 times within that 30 minute game. The lowest cool down flash can have is on Howling Abyss were it can get to as low as 142.5 seconds and to have this short cool down you need to have the item Ionian boots of Lucidity and the rune Cosmic Insight which shorten flash's cool down by 15% in total but since Howling Abyss is ARAM your also get the Howling Abyss aura which adds 40% summoner spell cool down and this is on ARAM. The lowest cool down you can get on flash on summoner's rift is 255 seconds which is only reachable with the boots and runes i stated above.

Now I'm not saying flash is completely useless it sure can save you or get you a couple of kills but only once every 5 minutes. I use to always use Flash don't get me wrong it was had to be one of the two summoner spells i would use but i now i never use it because i realized how little you get to use it (well unless your Zoe then you can use flash all the time). But maybe its time to change the META up a bit maybe its not, all I'm saying is that don't get up someone for not using Flash until you try it for yourself because it really shouldn't be the main summoner spell anymore.
