Defence change for bombers

While the unofficial classes of knight (striker, gunner, and defender) each have a 5star armor selection that allow you to choose a defense type to best help you on your mission the Demo lines does not.
Suppose your party reaches a Lichenous Lair, the gunner will choose the Justifier set, the defender will choose Ironmight, and the striker will choose Skolver. However, you as the bomber have nothing but sets with normal and elemental defense to choose from, this means that every monster you encounter on this level can do a large chunk of damage to you. This lack of selection among resistances is what actually scared me away from playing bomber when I was a lower ranked knight.
Bombers have very little choices when it comes to defense; you either choose elemental or elemental with shadow (kat helm). This narrow selection means that piercing damage is the number one threat to a dedicated bomber, followed closely by shadow damage.
In order to balance this I would suggest:
Change the Mad Bomber set from elemental to shadow resist.
Change the Bombastic set from elemental to piercing resist.
Leave the volcanic and mercurial demo set alone.
What are your thoughts? Are these viable changes or should SK plan on releasing a new set or two to fill these gaps?

They need to first nerf Chaos set IMO. Give it only CTR and DMG bonus to swords and guns only. This way mad bomber can come back as a viable set.
I'm not sure how OP this is going to sound but there should be a shadow defense version of Volcanic Demo set without the fire resist. I don't what status resist it should have but maybe shock or poison?

Chaos set already has a wide variety of status penalties so instead of nerfing it why not cut the penalties that the mad bomber set has?
As for a new CTR set with poison and shadow resistance I would certainly like that set. Seeing as we already have a shock resist Mercurial demo I don't think that would be too much of a change, perhaps instead of shock why not stun and curse resist in order to give Demos an option for those status.

Kat Hiss armor.
Improvise a Pierce demo set with Mercurial jelly. More or less half of what Mercurial Demo offers.
>I can salvage Mad! Just change from X to Y! Buff Mad or Nerf Chaos! etc
Mad is just another artifact from an earlier phase of the game, when if you wanted Bomb charge or Bomb damage you were forced to get both at the same time along with the weaknesses. The game matured with reworked Volcanic, Bombastic and Krogmo trinkets liberating us away from Mad.
Chaos reeks of being someones 'muh glass cannon' pet.

Your not limited to "class-specific" equipment. Go in with a Barbarous thorn sh.

Why would I ever Use more than one bomber set anyway?
other than resistances, which can usually be fixed with a remedy pill, I don't need more than 2
Bombastic is currently the worst, freeze resistance doesn't even really matter considering you get freed by someone if they hit you, which at the point where its bad to be frozen people are usually pretty sharp about that kind of thing
Mad Bomber has all those Negatives and it only really supports blast bombs that are more their for damage, I don't need a damage boost for something like Ash of Agni or Voltiac Tempest I need to place a bunch down to afflict everything with status problems
Mercurial is a gimmick set, the movement speed helps a bunch with dodging and weaving like your playing a danmaku game
in other words, Volcanic is the only really useful set of armour
however I agree with Mystrian, your not limited to class specific armour so you might aswell take a Volcanic helmet and silvermail/quicksilver armour to round out your defences

I agree. They should either change the defences for Mad Bomber and Bombastic sets, or make 2 new ones with pierce and shadow protection. Bombing is quite fun, but when i took a peek at the bomber sets i left the idea. Pure elemental and normal defence, no shadow nor pierce. Devilites are a bomber's worst nightmare. You are not forced to use class-specific equipment but if swordsmen and gunners have their class-specific equipment why should bombers be left out and be forced to get another line for pierce and shadow protection?

Replace Bombastic with Blast Cube Helm/Mail for piercing, replace Mad Bomber with Bombie Helm/Suit for shadow.
Or, just make Bombie their own sets, though DO replace Bombastic with Blast Cube.
All that changes is things fitting thematically and resistances. Otherwise, straight for the resistances. For those with accessories, try to keep the basic "theme" of the originals in some way.
I was going to say to also cut Mad Bomber's elemental resistances into Piercing, Elemental, and Shadow, evenly divided, but that's a terrible idea, so screw that.
I can totally understand what you are saying. I believe that after the Gunner Update, the devs on th SK team should work on a bomber update. There are plenty of swordsman sers out there and more gunner sets with the GU so whynot a bomber update? In my opinion bomb are one of the most underused weapons ingame
