If you want to make money, then explorer is probably the best option. Crafted stuff doesn't really sell good enough, with some exceptions at max tier, so you'll have to rely on gathering materials for selling. And only the explorer has two gathering professions (farming doesn't really count as gathering professions IMO), while all others need to use their collected materials to improve their production skill, and then buy some for their other production skill.
But if you want to actually craft stuff to use for yourself, then explorer is a poor choice as you've noticed. You'd probably want to pick armourer, armsman or tinkerer instead, with the last likely being the most profitable of the three later on (everyone can use 7 pieces of jewellry, only 3 classes can use heavy armor and characters can use at most 2 weapons).
