I have had my mark for 5 years, bought with 36k now have 93k miles. I never had a shift problem at all. Even after adding a chip I had no problems. I didn't find out about the 1-2 problem till after my 60k service and figured I would do it next time. Well, next time was here and had it done. The springs were broken but luckly the bores were ok. I don't see any difference with the 1-2 upgrade in shift quality but I have read about the damage it can do. The lesson is: regardless of how it shifts, get to 1-2 upgrade done!
