I'll note that, even without any new arts, we can't fit everything we want to do. We aren't full up on Sect Jobs, there is no challenge research, no exploration, etc. We already have our hands full; why try to pick up MORE things to juggle?
We'll
never manage to fit in everything we want to do. Our hands will always be full. This is the nature of any given system that relies on Action Points or a derivative thereof.
Arts are the most direct way to increase our available strength and have knock-on effects by improving the training of related skills, greatly encouraging a derived skill to develop from the lessons taught by the Art in question.
First of all for the upgrade, DLS is far better, being both grinning moon and explicitely an art based upon a trial made by that moon.
As Far as ENM vs DLS is concerned, ENM directly boosts Stealth and Spiritual Hit, which DLS
doesn't do. DLS is an excellent defensive Art, but it isn't currently focused on Stealth or offense, while ENM does both of those.
ENM's a stopgap for training Fade and a shoo-in for our Stealth Suite - one piece of what I consider the 'minimum' of SCS, ENM, and MNO for a 'complete' set.
SCS counters physical tracking, MNO counters spiritual tracking, and ENM provides us with a soft 'reset' button should an infiltration/scouting mission go awry.
I'm hoping to use ENM to bump our Fade to the Mid-C range and then push it to B with DLS, ideally with DLS doing for Fade what SCS did for Dodge. It'll depend upon what we get out of the Second level of the Archive, if anything.
I agree for the time but I don't believe we need to get a fade art right now, and getting it on the second level of the archive allow us to train fade for a far longer time (up until the tournament, which is when fade will truly be relevant).
Err, we kinda do need a Fade Art if we want to advance into Fade B in a reasonable timeframe. Arts push learning Skills as a kind of training wheel - see the way SCS taught us Sable Grace - and going without access to Fade B sooner means we won't have the option to hit Fade A - and our base Domain improves the S. Avoid, S. Armor, and C. Perception of allies by one rank, up to LQ's.
Having Fade A means we can plausibly have S-rank Spiritual Avoid, meaning that our closest allies (who we will most likely group with for the Inter-Sect Tournament) will obtain the most benefit from our Domain.
A Second Level Art won't be particularly relevant, either, given that we'll most likely master it by Green 4 - and we'll be Green 5 by the Tournament, barring a serious fuck-up on our part.
Tournament's turn ~19, after all, and we should be Green 3 by no later than turn 6 and Green 4 by no later than turn 11, resulting in Green 5 by turn 16-17. That leaves enough time to polish up the last levels of Archive ~3 Arts (if any) and bring whatever else we have to their Green 5 soft-caps, basically skipping base cultivation those last few months.
