Changing Roles for 5.0?

[Singularity]

So beyond the OP...

As someone considering trying a new role/job, looking for opinions/advice.

If you *were* trying a new role/job and were really foggy on most of the boss mechanics, would you want to:

A. Ask an FC to help do run of content with you while you learn to get support/advice

B. Find/create a "take it easy/learning" linkshell?

C. Keep putting up "role/job learning" party finder groups as you level/learn to find people willing to explain/be patient

D. Just jump into DF a lot and do your best

(yes of course you can look up guides but that can only go so far, so this is in addition fpr actual live practice/guidance)

By "boss mechanics" do you mean job mechanics (the question doesn't seem to make sense in context otherwise)?

My usual approach to learning a new job is to start with a striking dummy. I'll look up the optimal opener for it and practice 'til I can do it reliably. This gets me accustomed to where the skills are so I can hit them without thinking and highlights any glaring issues with how my hotbars are laid out. Openers are good for this since they're usually the most action-intensive part of the fight.
After that I would start taking the job into dungeons. There's not a huge amount to keep track of and if I mess up a mechanic it probably won't have major consequences. I take doing the mechanics seriously though, since the point is to practice being able to do the job mechanics while also handling fight mechanics. If I can, I'll ask friends to run with me that have experience with the job/role in question so I can ask them live in the moment if I encounter a situation where the best thing to do isn't immediately apparent.
So I guess in answer to your question, a combination of D and A.

I mean in addition to learning the job having to learn the fights. For example, imagine a tank that doesn't know where to position the boss, which abilities are tank-busters, etc.

Ah well, then I'd still stick with a combination of D and A. It's hard for stuff to go catastrophically wrong in a dungeon as long as you have at least a vague idea what the job you're playing is supposed to do, but having friends along helps (and is also more enjoyable).
