Hmmm...
- true, you don't need alljobs for good XP, you can get good XP by going pure something too, but you get awsome XP automatically by being alljobs not just from jobs but from quests too
- respeccing to alljobs from something is the worst thing you can do - you should start as alljobs and respec into something else from it, not vice versa
- sorry but I cannot reveal publically the certain moneymaking strategy, please wait for w15 where I'll show you that you can get 1 million $ in just 3 months of play. can you do that with travelling merchant job? yes you can, actually. how, that's another question.
it's like a question can you get the gold gun without premium... yes you can - definetly if you started as alljobs you can, but I'm not sure if you can by starting as another build.
- not average in fort battles, I was #1 damage dealer on w15 with alljobs build in many fights. although westforts.com is a crap site, you can check it up there. and yes, I've been a pure trader for a few weeks in my "career", were in fort fights with that build and pretty much sucked.
on the other hand with alljobs build, you're a sniping monster. you're not better than a tank of course, but since you become filthy rich with the cash you've earned previously, you'll respec into HP monster later. Where you'll put all those bonus SP and bonus AP you got from being alljobs and solving quests.
Look, I'm not saying alljobs build is the best thing in the game. It is not. There is no the best thing. There are a few good builds and the question is only what do you want to accomplish in the game. When you answer on that question, then you better pick a build that will bring you quickly closer to your cause.
