Basically, while most may not admit it, Riot is balancing champions based onalone, and it's a miracle not to see Flash on at least 6 out of 10 champions in any game.
So many people have tried to think of a way to solve this, and are still trying to find a way to make it balanced. Sadly, extending the cooldown or nerfing the range will not solve Flash's problem as a no-brainer-get-out-of-jail card for basically any situation.
So what should we do about it?
While I talked about it in chat with several friends and members of mine, we agreed on something like this:
- 45 movement speed = 585g
- Total Gold Value = 585g
- require at least 715g to be cost-efficient.
So basically, what does this mean to champions? The boots itself is quite costly, but is still a choice for champions while Flash isn't truly removed from the game.
While most champions would easily pick this over any other boots because of how good this ability is, an extra unique passive is applied to the holder of this item, increasing the boot's cooldown. This means that champions like Kog'Maw, Sona and Galio benefit from it because they don't have gap-closers; Champions that have non-spammable gap-closers like Ahri, Warwick and Renekton are okay with it, and gap-closer-spam-happy champions like Ezreal, Lee Sin and Kha'Zix would hardly see much benefits from it. Movement Speed modifiers wouldn't count towards the cooldown increase, because these abilities can't really jump through walls and so they should be perfectly fine.
An alternative, if we don't want an item, would be like this:
While I'd like to propose this to Riot, I'm not an NA player, so the message couldn't be spread. If a Samaritan would kindly forward this to the NA forums, I would be more than pleased.
Edit: Regarding abilities that allow you to gapclose multiple times in one cast of an ability (such as Ahri and Riven), they are counted once.
Edit2: Since some people can't grasp the general idea, I'll simplify it without values, it's adjustable.
