Vma lightning vs inferno backbar

Exodium

Getting back into the pve game after a bit of a break and when I last did it properly the vma lightning was in most situations better than the inferno backbar.

So with the recent off balance changes, in what situations does the lightning staff outperform the inferno backbar?

I'm looking at comparisons for both solo content (vma), dungeons AND trials, as well as explanations of whether some classes do better with the lightning staff over the inferno.

Thanks

Lightning will outperform in most cases, when in your group no dk is running engulfing flames. This buffs up all fire damage to the enemy by 10%. Also with an AS staff you have a high uptime of burning, which increases the damage of wall of elements by 20%. For this also the burning from other players count, so actually its a constant damage increase. Anyway in trials minor vulnerability is mostly given by the few lightning damage sources from healers and sorcs. So lightning staff backbar mostly will only do better in a target dummy fight or in a dungeon with a bad group not providing much lightning damage or engulfing flames.

Lightning does well in solo, 4-man dungeons, and groups that don't have many sorcs. Sorcs usually run the lightning staff due to their damage passive. Otherwise, fire does a little more damage since fire blockade does more damage to burning npcs.

In general, for trials it is lightning for sorcs and healers, fire for the other dps.
In solo usually lightning is better due to better minor vulnerability uptimes which boosts all dps.
In dungeons, if you have another sorc or healer using lightning blockade and you are not a sorc, fire is best. Otherwise lightning.

Also note that dunmer get higher fire damage.

In my opinion, in trials you dont need more then a tank (already using it for crusher uptimes), and the 2 healers running it so the magicka dps should run fire blockade
