One of the major cons is lack of access to resources. Such as ice rinks (there is, for instance, only one in my state, which is half again the size of Texas), or ice that isn't constantly full of other people and thus a poor or unsafe training environment, or professional choreography, or the funds to pay for professional choreography/costumes.
Another, less recognised issue: if you're based in the southern hemisphere, as a lot of small fed skaters are, the entire structure of the skating year is antithetical to the rest of your life. Given the age range of most active skaters has them still in education, for example, while their northern hemisphere counterparts are filling in their long school/uni breaks with multiple short or long training camps, southern hemisphere skaters have got two or three weeks in the depths of winter to travel to a new location, acclimatise to a hot environment, train, and head back home in time to restart study. That's not good for either their skating or their study, or their general wellbeing. And then think about how disruptive the competition calendar is, and how hard and expensive even getting to those competitions is too...
