Firstly...
IF anyone is trying to propose any balance on the basis of push raiding then that's misguided.
It's a very specialised space and often requires very specific builds and planning.
Those who engage in it are skilled, no doubt, but a vanishingly small proportion of the player base.
Secondly...
In terms of overall balance, whilst that can be improved, I think we need to accept it can't ever really be fully balanced, and moreover that that's a good thing!
Of the three generic build styles: Ranged, Caster, and Melee, there is always going to be one that is generally better and one that is generally the poor relation.
For example if we somehow buffed casters to be more or less as powerful as ranged, then melee becomes the poor relation. It's already behind ranged after all.
All we can really hope for is that each may get it's place in the sun for a while. Casters had that for a while, but it's now ranged and has been for some time. It's probably time to have melee top of the tree for a bit and maybe caster goes above ranged too.
I'm not sure how else to approach this, as unless your take a longer term and dynamic view of balance, you're left with a once and done static approach that simply won't work, as it inevitably leaves one at the bottom of the pile and those who prefer that style will be unhappy.
At least, if the Devs adopted a more active approach to for want of a better term balance rotation, then folks concerns and disappointments could be tempered by knowing "this too shall pass".
What's clear IMO is that the meta has remained too static for too long.
The challenge and opportunity arising form this will be interesting, however I'm sure that as with any change there will be winners and losers. Hopefully folks are wise and mature enough to accept that inevitability - I have my doubts!
So I'm looking forward to this apparently major balance pass. It is time for change. And I say that as a pretty much exclusively ranged player.
Don't cry folks - adapt!
Or at least do both.
One would think the Devs would have all sorts of tools to measure DPS in-game? While one style is always going to be better than another one, could they at least get them within some +-25% range?
The disparity they allow just kills any sort of build diversity that used to make the game great.
1. Generate a maxed-out character for testing
2. Take some builds from caster posts, some ranged/melee builds from other posts
3. Generate the gear and gear them out
4. Do tests on purple-named mobs on Elite or R1
If they wanted to, they could get things a lot closer than they are.
I am not talking about non-DPS builds, but for builds that are designed for DPS, they should be within some sort of reasonable variance.
To me, you have to go back to the fundamental systems.
1. Melee, Ranged, Spell Power
2. Critical damage
3. Critical Multipliers
4. Base Damage
5. Helpless damage
6. Single Target vs. AOE
7. Rate of attack
Once you have the styles balanced, then you can look at individuals within each e.g., bow vs. repeater, swf vs twf vs thf, etc...
It's boring to be forced into a handful of builds for years.
