I think that this sort of question falls under the Good Subjective guideline (but more on that later). There's no One True Answer, but people who have done this sort of conversion can show what they've done and how they'd do it again, and the best answer (for you) can be accepted, and the best answers (for the community) will be upvoted.
The main issue in this case, I feel, is that 5e is too new. One of the main tenets of Good Subjective that makes those kind of questions and answers useful is the ability to back it up. This requires solid experience. Since very few people have played 5e, and fewer still have written up new classes, there can be very little solid experience with this process at this point in time. Answers will probably be "I read the playtest packets and I think the best way could be to do...", which falls under Bad Subjective, and probably closed as Opinion-Based.
So the bottom line is that I think the questions are fine, and a good fit for the site, but that 5e questions, specifically, are likely to attract bad answers at this point. Not all answers, of course - there's already a 5e homebrew community out there, and answers from those folks would be welcome, but the pool of possible contributors is small, and care must be taken to prune out the bad answers quickly.
The best way to do that is to explicitly state, in the question, that you'd like solid experience to back up any answers, and promptly challenge any unbased answers to prove their experience. Don't wait for the mods to step in and possibly close the whole question, but be proactive in demanding specific criteria for answers.
