Was thinking about this the other day. Should they? They are a class with inherent trapping abilities. Wouldn't a means to avoid said traps make sense? To me it does...with some caveats. First in deference to our rouge friends it would not be an auto-granted feat. It would have to be bought with a feat slot. Second, no improved evasion again in deference to our rogue friends who, by all rights, be the height and experts at evading. I see it as one of several ways:
1) just be in the class feat list that artificers have...to easy as far as I'm concerned
2) be in the class list only but with a level and feat requirement. I would think level 10 and either insightful reflexes feat or a base dex of 17 (numbers subject to discussion)
3) be selectable any time once level and feat requirement meant as outlined above.
personally I think option 2 should be required. It's costs either two feats or one feat slot and some build points to get. Not cheap by any means.
