TL;DR
Restructure glyphs
Add breakpoints to glyphs
Add glyph codex
Add aspects to glyphs
Example
This is my first real post on here so I apologize for not knowing the intricacies of how and where to tag or post.
The idea I’ll be proposing will be cautionary to implement to avoid not a power creep but a power leap.
As it is the devs are adding significant aspects and uniques to the game every season to which this idea will help utilize most of them to really boost builds in a defining way.
First take all the secondary affixes off of the glyphs and make them all magic (blue) glyphs.
Second increase max level to 25 and put all secondary affixes as aspects into the codex or into a glyph codex.
Third add breakpoint levels every 5 glyph levels.
Fourth make unique aspects able to go into the codex or glyph codex.
Levels 1-5 are magic glyphs(blue)
Levels 6-10 are rare glyphs(yellow)
Levels 11-15 are legendary glyphs(orange)
Levels 16-20 are sacred glyphs(burnt orange)
Levels 21-25 are ancestral glyphs (blood red)
At each of the breakpoints (between 5/6, 10/11, 15/16, 20/21) you’re able to add an aspect from the codex or glyph codex. This will have to be max roll or minimum roll aspect to control power creep at each level. This will let you fully fill out builds and utilize majority of new uniques and aspects.
Example: Sorcery glyph Elementalis.
Main stat (can not remove)
Paragon nodes within range gain +x% bonus to their Non-physical damage and damage reduction modifiers.
Rate aspect (added after level 5 optional) tal
Rash aspect: for each type of elemental damage you deal ,gain x% increased damage for 4 seconds. Dealing Elemental damage refreshes all bonuses.
Legendary aspect (added after level 10 optional) Edgemaster’s aspect: skills deal up to x% increased damage based on your available primary resource when cast, receiving the maximum benefit while you have full primary resource.
Sacred aspect (added after level 15) elementalists aspect: Core or mastery skill cast at or above 100 mana gain a x% increased critical strike chance.
Ancestral aspect (added after level 20) Elementalists glyph aspect: dealing fire, cold, or lightning damage to an enemy increases all damage you deal to them by x% for 10 seconds stacking once per element.
Now all these modifiers will be on one glyph and stat requirements can be adjusted to fit. This makes room for added new and seasonal aspects and uniques to enhance builds then you can use gear slots to craft completely new and useful gears to really make the build your own and unique from another.
With the game going towards AoZ and/or GR end game this will increase power and can also increase defense in similar manner to push into a torment X or XX (for lack of better reference) level dungeon/rift.
