you should have a offensive job to get rid of the wolfs, and then draw ur bottanist job.
The game want us to have multiple jobs, and the endgame goal is to have them all, but a fighting job at start is necessary for that kind of stuff. That or having the luck of some one killing mobs close to your goal :P
Come release i know i will be leveling all sorts of jobs and this type of situation wont be a problem but i thought SE stated you could do whatever you want in this game and "just" be a gatherer.
There had better be ways of avoiding aggro (i.e. sn/inv tools) come launch because it will suck in a lot of circumstances if not.
EDIT: If i recall i tried switching classes during a leve once. And it wouldnt let me. Please clarify if i am right or wrong on this.
Yes, they said that if all you want to do is be a crafter, you could do that. They did not, however, say that you would be able to meander the hills and fields, gathering to your heart's content with impunity. Anyone who thought that might have been the case should have done a little more reading and a little more thinking because in most MMOs, aggro is a major part of the mob behavior, and at no time did SE ever say DoH/DoL would be effective fighters. You can do levequests for your crafting professions to skill up without ever having to leave town and use the gil rewards to put towards further mats and build your empire that way.
XI was the only MMO I've ever played where you could bypass aggro (almost) altogether with Sneak/Invis, and it was a necessary mechanic in a game where everything required groups. I don't think it will be nearly so necessary in XIV. If you can't get to the node you want because of aggro concerns, you move on. That's just how it works.
