1. Frozen orbs are (and always have been) purchasable on the auction house.
2. You can always join a guild or run a PuG
3. If you are a solo player do you really need that fancy purple gear? Without playing with other people there isn't much to do that requires a high level of gear.
Stop judging. And I'm not saying that because I think you're a Paladin. Even solo players like to have a goal and leveling a profession to make the best gear in that profession is a laudable goal. Just because you and I may like to raid, or George and Fred may like to PvP, doesn't mean everyone has to join a guild, raid, or PvP.
Same goes for the others who are advising that the OP doesn't need the top gear in the game. He's not asking for the top gear, he's not asking to have Naxx gear, Eye gear or OS gear available to him. He's asking why he can't make the best gear in his chosen profession. This forum has never been filled with leet before, it has always been tradeskill-friendly answering any tradeskill-related question without any negativity. Take the leetness to the general forum or your class forum.
OP: codexia has really summed it up. There are an awful lot of dailies and a good many of them take no time at all. I guess that's the only path left for you. Good Luck!
