Less duration gem change is hurting Lightning warp

Less Duration Support
Now gains 0.5% less Skill Effect Duration per 1% gem quality (from 0.5% reduced Skill Effect Duration per 1% gem quality).



Now need Awakened swift + eternal lab enchant for it to get at similar value but need now 114 Dex. Who can get 114 dex as a caster witch? Too high investment.

Please consider changing LW gem duration because of Less duration gem change.

Unless you start stacking reduce skill effect duration.
And if less skill effect duration is stacked with the gems and not as another "less"

New

let say you have 49% "LESS DURATION"+ 10% "LESS DURATION" = 59%
You have 100%-59% = 41% remaining duration.
Now let add swift affliction
41%*0,85 = 34,85% remaining duration.
----------------------------------------------------------------------------
Old

You have 49% "LESS DURATION" + "10% Reduced DURATION"
You have (100% - 49%)*0.9 = 45,9% remaining duration.
Now let add swift affliction
10% Reduced + 15% Swift affliction = 25%
51%*0,75 = 38,25% remaining duration.
----------------------------------------------------------------------------
Usually bonus from gems stack additive with the bonus from the gems itself.
Unless there suddenly 2 line of "less duration" and in that case it a nerf.
Otherwise it a pretty huge buff unless you invest massively in "less"
duration.

Lightning warp benefits massively from reduced duration, not less duration. The game adds all sources of reduced duration for Lightning Warp first before using less duration modifiers.

A typical setup of achieving 100% reduced duration with lightning warp in the 3.10 patch is:

Lightning Warp - Less Duration - Swift Affliction and the Eternal Labyrinth Reduced duration of warp enchant (30% reduced duration).

This achieves at total of 104% reduced duration, but reads as 100% because you can't have negative duration.

Lightning warp at 20/20 inherently has 49% reduced duration, so if we link the current Less Duratiion at 20/20 (10% reduced duration and 49% less duration), Swift Affliction, and the Eternal Lab enchant to Lightning Warp, the calculations goes as followed:

(100%-49%-10%-30%-15%)x(1-0.49)=-2.04% remaining duration (read as 0%)

With the new 3.11 Less Duration gem (59% less duration) you get:

(100%-49%-30%-15%))x(1-0.59)=2.46% remaining duration

It may look insignificant at first, but considering Lightning Warp reads both cast speed and your character's movement speed, it can get absolutely devastated by the many slows in the game (Elder's sucking attack to list one). It gets doubly affected by such debuffs, making this ridiculously high opportunity cost setup absolutely worse than normal movement skill setups such as Dash or Flame Dash.

To make up for the last 6% missing reduced duration, you need to either use an annoint for the new Window of Opportunity node or obtain Awakened Swift Affliction, critically an endgame support gem. Both of these raise the opportunity cost of using this skill even more.

It's not doing any favors for other shit like Storm Call, either.

For what it's worth, it's a huge buff to Heartbound Loop CWDT builds. Previously, the timing of a hit had a 50ms out of every 300ms window of triggering a CWDT Skeleton out of rhythm, causing 528 extra damage with the hit and cutting an average of 25ms off the next cycle — so basically 10% more DPS for a quarter of a second for an average of ~16% chance of 528 additional life lost on hit, not a very good trade. With 58% less duration instead of 50%, the chance of that is less than 1%, and there's 19% more cycle speed.

Blessed Rebirth, the cluster gem notable, was also a recent buff to the archetype, making it so the chain couldn't be broken by Skeleton death. Especially good when granted via Megalomaniac, since the build has no use for increased minion life.

If I had to guess, this is what GGG is trying to push. I don't think it would make the build viable, because it was garbage tier before, but two (and a half, considering Megalomaniac) changes in two consecutive leagues doesn't feel like coincidence to me.

Probably an oversight

I sure hope so! Also a big fan of lightning warp so I want it to be good too :(

the tree now has 2 x 5% reduced and 1 notable 15% reduced skill effect duration

there is a mistake in this thread regarding less duration "stacking" though

less is basicly a negativ more multiplier
this means less duration from different sources are multiplicative to each other not addative

so 49%less + 10%less from a different source means a total of 45.9% remaining duration not 41%

lol no, the quality bonus of the gem is not a separate source from the gem itself

I think he was talking about milorius' post which seemed to say "all sources of less duration are additive" which is like a separated "reduced" group.

as you can see 10% less duration and 49% less duration is not 59% less duration.
Or perhaps he didn't see the new gem itself at 20q which had 0% reduced duration .
