I'm just wondering is it really worthwhile to actually obtain the data for recipes that may be wiped out in the upcoming version updates... But in terms of Alchemy the materials needed are no longer dropped in the game so they wouldn't really be the best method to leveing up.
You have a point... a lot of the alchemy recipes on that list may not be around after future updates. Imo, it doesn't hurt to spend a moment recording how much exp you got if you happen to synth something on the list.
