Let’s start with my experience on the class I play 4 ShadowHunter:
Demonic level 10 damage gem and lvl 9 cd LoS-18
-Demonic impulse crit spec Salvation ilvl 1551 all quality accessory 95+ 5x3 (demonic, cursed,grudge, keenblunt, adrenaline)
-Demonic impulse spec swift Hallucination ilvl 1485 quality accessory 85+ 5x3 double build (demonic, cursed/raid captain,grudge, keenblunt, adrenaline)
- Demonic impulse spec crit Salvation ilvl 1450 quality accessory 70+ 4x3 1x2
-Perfect suppression( not playing it anymore) crit swift Entropy ilvl 1460 4x3 (it had gems level 7 now he doesn’t have anymore )
(Other classes scrapper tai 5x3 1475; sorc igniter 1475 4x3 1x2, artillerist barrage 1445 4x3 1x2 :all of them lvl 7 stone)
Problems of demonic impulse:
-Lack of Crit rate. In salvation build while all other transform/hitmaster/costant dps classes (artillerist example since they run the same build) they can hit 75%+ crit rate without problem if they have adrenaline lvl3 because the crit rate buff from the class transformation/engraving is higher DI hits 72% if u have a chad bracelet
example: artillerist gets 40%from engraving+15 %from adrenaline +18-20%crit stat without bracelet Demonic 30%+15adrenaline+18/20%from stat without bracelet ; Damage increase artillerist get’s is 30% from fire power meter + 20% from the transformation engraving Demonic gets 0%
-Swift hallucination kinda solve the problem of crit rate but if u do so u will lack in dmg watch artillerist example
(in regards of the dark version of the demonic form i don’t mind I’m not blind i can see it everywhere and if i need i pop outline)
Perfect suppression: have big problem from skills all beeing multihit on equal dmg x hit that u have to be inside the boss to not lose dps/hits( watch tai scrapper multi hit but the biggest hit is at the end), From damage not beeing competitive ( at least this is sorted with korean balance patch ) and most important the low gauge gain makes it realy unplayable (not hard is just not playable) compared to other back attack multi hit classes.
If u are not main and u just have an alt Demonic i would invite u not to not speak unless u have the DI alt at 1540+. Because up to vykas/clown it’s fine u can even compete for mvp if u have pepega teamate after brel is where u realy start to notice the problems.
And for those that will say " Yes but shadow hunter have a higher uptime" yes on paper but not on legion raids where u have to position to dodge to do mechanich the uptime is way lower and other constat dps class balance this with higher dmg base stat and bigger engraving class buff or a second gauge that buff damage.
Conclusion:
Demonic: Lack of critrate / dmg for the real uptime in raids
Suppression: To much multihit and Gauge meeter gain too low
