| Description | Note: This probably applies to all non-stacking RDPS, but I have only observed this while leveling my engineer with Napalm Grenade and Phosphorus Shells.
When multiple non-stacking skills are cast in the same area, only one will actually do damage. The selection logic for which caster does the damage seems based only on the skill level of the ability, ignoring all ability damage increases, crit, etc. For example, an engineer with no ballistic skill, no crit, but maxed grenadier tree will be prioritized over an engineer with max ballistic skill, high crit but fewer points in grenadier.
Ideally the selection should be based on the highest damage one (e.g. calculate total damage bonus of all casters and pick the highest damage one, or some other formula involving crit chance too, etc).
It could even roll damage of all the channels per tick and pick the highest one, so that stacking AOE will give some effect since every caster has their own crit roll, giving a chance to increase the overall damage slightly. |
