Yes, there are mages that will use the current Phase Rush - but that's not the point. Riot could put literally any effect in any tree and, sure, there would be some examples of people who use them. The point of having different paths is suppose to be about different fantasies. If a mage wants to have a more hit-and-run playstyle - they should have to make the deliberate choice as well as make the associated sacrifices that comes with taking the Slayer Path, instead of the Mage Path. Riot shouldn't just be putting hit-and-run runes in every path: that defeats the purpose. If you'd read at least as far as Resolve, you would have seen that this is a major qualm I have with the current implementation of the rune system and it's the reason why Resolve feels so lame: the best defensive options are granted as minor runes in the other trees (whereas it should be that if you want a defensive pick, you should be going Resolve secondary). Paths should provide gameplay identity - at the moment Phase Rush is a Slayer rune, Riot showcased it being used by a Slayer, and yet it's not in the Slayer path.

And sure, using it as a free Boots of Mobility is a use-case I didn't compensate, even if that use-case seems more an unintended side effect of the ridiculous duration more than anything intended. However, I don't think a rune solely around both roaming and getting into a fight would still be a keystone - so I suppose I could swap its position with Mercenary. Although, Ingenious Hunter kind of already fulfils the moving-between-lanes-quickly niche. It's kinda hard to have an informed debate over what I've done, however, when you've not even read beyond the path that happened to be alphabetically first - my Sabotage path entirely caters to roaming champions and junglers, so the idea of adding a roaming keystone to Domination just sounds like it falls into the same bad-design-space as Phase Rush in the Mage path. While I did not fully compensate Predator's free third summoner spell, Ghost, it does have other tools - and I would sooner add that free Ghost to this path than reinstate it to Domination.
