a very nice beginning, this will make building more simple.
as for other thoughts and suggestions …
Solael’s Devourer - I’d like to suggest adding some flat mana regen to it (like 5-6). this is a 2h weapon designed for channeling skill, and FoI needs a metric ton of mana for sustain (w/o Voidsoul’s mods).
Targo’s Craft - wrote about it before. Some extra resists like elemental, bleed, poison would be great as set terribly lacks them. Also it would be great to see some more pierce support besides %damage, maybe some pierce flat to BA.
LD - wrote a feedback about it [Suggestion] Light's Defender set could get some QoL and damage buffs but nothing was implemented in the current patch. Set looks very underwhelming. Adding some phys res and +1 projectile to SJ (and also increasing flat on gloves) would be a great addition.
Stun Jacks as a skill still could use some love. Almost all modifiers are about adding electrocute, so I’d wanna see some flat bonuses to it too as it will help sustaining.
Forcewave - would be great if the 70% wd mod from green axe is moved to the skill itself as now FW is very-very mediocre and loses to all 2H skills. Some extra support to lightning/cold/ele FWs would be welcomed too.
Catasclysm set - [Feedback/suggestion] Cataclysm set could get some serious buffs wrote another feedback about it. Set is still trash-tier and lacks useful conversions and bonuses to become viable.
Spellscourge set - the resists change on shield was meaningless as neither vit nor bleed res are needed. Better add some phys res on the shield (6-12%), increase a bit LL on Devastation. Maybe add some RR proc to the set (with % or -% RR as build still struggles w/o it).
Mageslayer set - could surely get some phys res too.
Blazeheart - can’t stop saying that RR mod to SS is cancerous and having 2 active RR skills on a melee build is PITA (and one of them has 6 sec cd). So maybe it will be moved to Ill Omen or sth like that.
Mythical Vortex of Souls - adding aether RR to Wind Devils would be cool for aether shaman builds (ritualist and druid).
Hyrian constellation - wanna suggest changing its completion bonus to 2 purple/green instead of blue. maybe remove retal and add more ele damage to it.
Stormrend - some AS would be cool.
