Flash is on a 5 minute CD. Why is everyone so butthurt about a summoner spell that you can easily waste?
i'm not being butthurt about it. i'm saying that champions that already have more than one flash/dash/blink etc. shouldn't be able to take it because they don't need it. Why would you need a 5 minute cooldown flash when you have a (for example) 14 second one built into your champions kit?
If Riven couldn't take Flash she legitimately would have worse team fight potential than Shaco or Tryndamere, lol.
