Cause that certain wizard guide is outdated 2018.The game has progresses a lot so it makes old guide pretty much out dated and isn't keeping up with the current meta.The unfinished guide is an updated version of the guide which make more sense to put updated guide first then put an old guide
Not sure what you mean "the unfinished guide is an updated version" when it has about 1% of the required content and basically reiterates what's already on Sylver_Aura's guide. Actually, it's nothing besides subclasses and skill descriptions so that might as well be nil. Her guide was recently updated and, even if she didn't, 2018 is hardly "outdated", so to embellish a far-from-complete guide yet minimize a complete is, in all honesty, quite discourteous regardless of whom may agree or disagree within OP's current editor group of its contents.
Simply because a guide is considered "outdated" does not mean that everything in it is to be ignored or considered inferior advice-- i.e. People have still referred to Desperae's guide years after it was made, as well as Phil's duelist guide which was at least useful for starting out despite the fact it wasn't anywhere close to current content. If this project is requesting help from the community and is intending to be a community project, you should value everyone's contributions equally regardless of when they were made, unless there's a mass consensus that a guide has a huge amount of info that is not only outdated but would be detrimental to progress if one were to follow it. Not to mention that for guides where the information is correct but just not fully up to date, it may just be simpler to post on the pre-existing thread and then link back to it for consolidation reasons (and to prevent players from having to compare guides and ask "so which one should I use?")
On other notes, the guide itself is not a bad concept, but currently it looks quite awkward when almost every class section is penned under the same 1 or 2 names as if they were trying to claim credit for initially authoring it / drafting the layout (especially the Lancer section, which has straight up nothing); if anything it'd be unbelievable that one or two people could author that many guides when even just 1 guide requires a veteran who has played that class for at least a year and knows it like the back of their hand. This isn't to say none of your current authors are worthy of any credit at all, but rather that you may as well pin your guides as the unfinished alternatives and switch to having the pre-existing guides as the main links for now--until your guide(s) are finished, or at least have the core concepts finished.
Secondly, there needs to be more thorough explanation on why certain things are considered "the meta" as well as more flexibility / openness to the idea that what's so often claimed to be the meta is not ideal for every situation-- i.e. double -DEF shred trophies VS 95 elemental + -DEF shred in instances where bosses have shreddable DEF (which is not every situation), Abyssal Naught bottom set failing to properly shine unless it is fully +30'd, utilization of gear tab swaps, Neqzal trophy actually being quite useful in S1+ dungeons where mobs have high EVA, etc.
That's all I have for now, may have more comments later. They are not meant to be purely disparaging remarks, but simply criticisms on what is currently published.
