seems to be able to find the minimium skill level for lvl3 quality. Get to skill 138, and your will have lvl3 quality tms. The rest is just about waiting for concentration which isn't a big deal since u are going to craft a few only. What I have done as pure f2p:
1. level JC to 75-77
tips: when getting to 7?, you'll need to craft many Nordorite Ambers. If you are having bad luck with prospecting for Nordorite, craft Timewatcher's Patience (24hr cooldown) which gives u a few Nordorite. If u can't wait for the cooldown, consider using another alt to pick up JC, u just need jc level30 to create Timewatcher's Patience, then u effectively reduce the cd by half.
2. get as much first craft knowledge point as possible, JC npc for +5, darkmoone faire for +3, random mob drop for +1
3. get as many +3 Knowledge treasures as possible.
(i have 24 only, Emerald Dream, Zaralek Cavern seems not availabel to f2p, Alexstraszite Cluster has 97% drop i am the one that didn't drop, damn you blizzard )
4. 30 knowledge to Setting (a must) for the Tiered Medallion Setting recipe
5. 1 point to Faceting for the Polishing Cloth during levelling (optional, depending on Nordorite availability)
6. the rest to Jeweler's Toolset Mastery for as many skill as possible.
7. quality 2 eternity ember is optional since we rely on concentration
8. no rep grinding, no special recipe, just all from trainer, specialization
Special gift available only to f2p:
1. create a separate alt on a separate trial wow a/c (wow1, wow2, etc) LINKED (important) to the same B.net a/c
2. ur alt still share the warband bank with the main even they are 2 separate wow a/c's.
3. but now u can open 2 wow clients and play 2 toons at the same time (multiboxing)
4. when mining ores, uitilize the ride-alone feature and have your main fly along with your alt (press alt-tab to switch window)
5. fly to the ores dismount with your alt and mine. Now your are mining with 2 toons, effectively double your yield.
