World Solving Rainbow Weapon Problem?

First of all, I am bad at expressing my ideas so if u are confused/dont understand.It is probably my fault.

So,what im saying is that current rainbow damage weapons deal way less damage comparing to expectation.
This is because most of the boss/players have rainbow defenses.
This is also why players tend to make rainbow defense build but stick with 1 elemental damage weapon just to pierce through others' def.

For example, archer players would rather choose rainbow build with single elemental damage bow over rainbow build with freedom.
(just cause freedom's damage is greatly reduced by all elemental def but single damage weapon only has to deal with 1 elemental def only)

This is one of the advantage of using rainbow damage weapon( doesnt need to switch weapon cuz it deals each elemental damage)
However,this is also one of the disadvantage
Cuz you only deals like very little damage for each element.
People would rather switch to another single element weapon for better damage/penetration which is more efficiency than using a rainbow weapon.

For suggestion: ( it maybe not the perfect but could solve current problem and encourage players to use more rainbow damage weapons)
1.The damage should be calculated like the (sum of elemental damage ) - (sum of elemtal def)
instead of current calculating method which is (fire - fire def) + earth - earth def) + ....
well actually,I dont know how damage is calculated so....
But you know what i mean right?

2.please help me brainstorm a better one :D

Mobs have weakness too though, so it can balance out. Also, you can use multiple weapons to counteract defences. But yeah, for Qira it's kinda annoying having to use bob's or whatever.

Can i quote u to my post cuz i think it is a great explanation for current rainbow weapon problem,

 

Or you could add neutral damage powders to apply on rainbow weapons ??

There usually isnt a problem using rainbow weapons on common mobs as they do not have all five elemental defense but when it comes to bosses, yeah its terrible

 

pvp also :I

 

bumpaaaaaaaaaaaaaaaaaaaa

 

There should really be a new ID (Yes, I'm aware it's not very likely.) that grants elemental piercing. Ex. +10% water piercing means 10% of the water damage ignores defenses. The ID should be a rare one with relatively weak effects, but they should be more common on rainbow things.
