G9 covering forms exist so people have a choice on how to breed their chocobo. People can either be minimalists and buy only what they need to to produce a higher grade fledgeling (those just looking to get the achievement ASAP), or they can take a chance and buy higher grade forms which could result in the fledgeling having higher stars earlier (those completionist-types looking to make a high star bird).

Don't suggest a change that would affect other players negatively just because you had a bad experience. It would be like choking on expensive food at a restaurant and then trying to get them to take the food you choked on off the menu, using "it's just as healthy as the cheaper food" as an excuse.

At its core, you're really just complaining that the achievement's text confused yourself and others (it's very important to include other people were affected by this as well), so the thread should be a suggestion to reword it to be less confusing, and that's it.
