It makes me so sad that you have to take such a useless feat (Mobility) in order to take this really useful feat.
It makes me even sadder still that you have to take Dodge just to be able to unlock said useless feat.
That's really it...don't have a suggestion for it, it just makes me sad that it's such a challenge to get a feat that is so helpful for my lovely Artificer.
*EDIT*
Side note -- the feats I'm thinking about taking:
Toughness
Dodge
Mobility
Point Blank Shot
Rapid Shot
Shot on the Run
Precise Shot
Improved Precise Shot
Mental Toughness
Maximize
Quicken
Imp crit: Ranged
