I'm not putting this in suggestions because it's not a suggestion yet, but more a poll of the community of what they would like to see done with the armor.
Right now, Wolver gear is simply the best armor for swordies. Mad bomber is arguably the best bomber gear, but Volc now has been fixed, so it's a solid alternative for those who want to bomb FSC (But it's use outside of FSC is severely less than mad bomber as far as DPS is concerned, less so with status effects). Nameless (now with extra seerus), is probably the best contender for gunners.
But then you have off armor types.
I personally own vog, skolver, nameless, mad bomber, radiant mail, heavenly, snarby, ironmight plate, all 5*, and cobalt armor (not yet 5*). I probably have some others I don't use as well, I forget and I"m not bothering to look now.
Point is: Cobalt armor and plate armor are just weak. I liked my plate before I had awesome UVs on my skolver gear. It did take less damage, enough to make a difference between dead or 1-2 HP left, so it did have a noticeable effect, and I offset asD with a trinket. But compared to wolver line: It's crap.
Cobalt armor is just about the same. It's not noticeably better defense than wolver gear, yet lacks any bonus at all. But how to make it truly an all purpose armor?
I was thinking I'd like to use it if it had say asi low all, and maybe damage low all boosts, when at 5*. The full set would then give ASI med all, and Damage Medium ALL. That's roughly the same boost any split vog/skolver armor would give, and actually make it useful as an all around armor set. Bonus is that it affects guns/bombs too some.
The big drawback: It is REALLY hard to max yourself out with these boosts. As a side though, it goes very well with other weapon UVs, since you don't go past max as easily.
Potentially, this could be a bit overpowered. One other possible modification?
Make it NORMAL DEFENSE only. But boost the crap out of it. Make it like 75% stronger normal defense, since you're losing 100% pierce. Thus, any actual normal/special defense will take a bar or three less damage in t2/t3, but the cobalt armor will truly be an acceptable all around armor, just not spectacular. (it would probably be something similar to taking 5* elemental hood with normal/elemental, and radiant mail with piercing/shadow, but maybe a little bit better overall).
I know there probably has been countless ideas for what to do with cobalt armor before, but I've not seen them in a long while, and I didn't feel like necromancy today. Also I'd like an honest discussion about player wants needs. These are just mine.
As for plate mail. I'm fine with ASD low. How about making this the CTR armor for swords we don't have? That would make sense. BIG SLOW AND POWERFUL armor. I could see CTR MED swords for each 5* piece on all plate mails. That would give you CTR MAX on all swords once everything is heated to level 10. And since you're sucking asi LOW, you could probably put movement decrease LOW as well on 5* sets for each piece. Thematically, I think that would be fitting, and I'd happily wear my plate mail for something other than a costume..
So. Tell me what you want, what you think could be changed, and if we get a decent consensus, I'll make a thread in suggestions once we get there.
TL:DR : Don't bother replying to this.
Cobalt should lose 30-40% of its piercing defense, then gain elemental and shadow defense to match. This would make it fit in well with the Spiral order weapons - decent all-around performance for those on a budget, but outperformed by specialized gear.
