One unit is totally fine for questing. Keep doing the 5 gem summons, especially on the current Fairy Tail limited edition gates. As for core units, any 7*/omni can carry you straight through the first like 15 maps. The six heroes are pretty obsolete now so I wouldn't suggest raising them. You can't really farm any good units. There is Mard Geer who is a free unit right now, but I highly doubt you'll be able to beat him with a one man squad with only a 7*.
