So with the upcoming balance patch, necros barriers will get their base values cut in PvP and WvW. While the contribution of healing power goes up.
I really like that change, and I'd like to see that change for pve as well with some tweaks.
So in order to not hardnerf support scourge, we would need to take the maximum barrier that we can get with, let's say 1500 healpower, then lower the base barrier value, but with 1500 healpower, you will get the same max. Barrier value as before.
So for the example:
Base barrier: 1000, bonus barrier with 1500 healpower: 3000 = 4000barrier in total
Now nerf base values of barriers:
Base barrier: 500
But increase healing power contribution:
Bonus barrier at 1500 healpower: 3500
= 4000barrier in total
Why would I like to see that?
It makes stacking full dmg scourges a lot less efficient.
And would open up for more dmg on necro.
