Not sure if this was worth its own topic, but I figure other people might have the same questions/concerns.
Now let's get to the point right away.
Could anyone tell me how necessary companions will be for questing, as in, will I need to have one/some with me for all/most/some quests. I would much rather prefer to level solo, since dealing with companions is usually just a hassle for me. I'ld much rather just use them as ways to sell my stuff on the fly or let them train professions than actually keep them with me.
