User blog comment:Leyrann/Riven Rework - Yes she may be able to use one/@comment-25912163-20150205231121/@comment-4834593-20150206161216

I'm just giving an example, not something you HAVE to do. You can't always run into the backline. For example, if you're playing against a competent skarner, you'll have to stay in the backline and either let him ult you while his team can't follow up, or go in after he ults someone else.

What you - to me - don't seem to realize is that, with Riven, it's basically impossible to get into the backline except by flanking. Her mobility isn't high enough to move through the enemy frontline if she doesn't flash for it. And flashing means the enemy team can counterflash and keep their range anyways. If she isn't just cc'ed to death.

Remember that you are supposed to only be able to use this buffed ability at the END of the fight.

And on top of that remember that numbers can be changed.
