That might be good if you have founder gunner weapon but if you dont plasma stream deals more overall damage dps.
Here's the math:
For example Base damage is 415-798
Plasma Beam 1.33x 540 - 1,077
Plasma Stream 6.85x 2,793 - 5,565
Pulse Shot 0.71x 291 - 581
Residual 0.64x 247 - 547
is Pulse Shot(15) X5 > then Plasma Beam (30) x5
Pulse shot will deal 291-581 damage * 5
Plasma Beam will deal (540+247)-(1077+581) or 787-1658 damage * 5
While Plasma Stream :
Pulse shot will deal 291-581 damage * 16
Plasma Stream Will deal (2793+247)-(5565+581) OR 3040-6112 damage
Pulse Shot (30)X4
Plasma Beam (90) x2
Pulse shot will deal 582-1162 damage * 4
This is where it's get tricky i dont know IF residual is damage is doubled or not when you use heat exchange if someone know for sure you can correct me .
Assuming it's not doubled:
Plasma Beam will deal (1080+247)-(2754+581) or 1327-3335 damage * 2
IF it's doubled :
Plasma Beam will deal (1080+494)-(2754+1162) or 1574-3916 damage * 2
Which will equal about 4488-10156 damage or 4982-11318
Pulse Shot (30) * 6 Plasma Stream (120)
Pulse Shot will deal 582-1162 * 6
Plasma Stream will deal 6,327-12,771 or 6574-13352
As you can see
Plasma Beam 4488-10156 vs plasma stream 9819-19743
that's a quite big diference
which will change damage by something like this
787-1658*225% = 1770-3730 damage (damage p.beam from founder effect)
3040-6112*225% = 6840-13752 (damage p.stream from founder effect)
Damage will change dependent on how many trash mob you kill in fight (i'll pick 1 for example)
5390-11025 -> (5390-787+1770) - (11025-1658+3730) = 6373-13097
7696-15408 -> (7696-3040+6840) - (15408-6112+13752) = 11,496-23048
1327-3335 *225% = 2985.75 - 7503.75 (damage from founder effect)
6,327-12,771*225% = 14235.75- 28734.75 (damage p.stream from founder effect)
Damage will change dependent on how many trash mob you kill in fight (i'll pick 1 for example)
4488-10156 -> 6146- 14324
9819-19743 -> 17727- 35706
i dont know how much the damage will change with multiple mob kill or pulse shot damage between beam/stream (too lazy to do math i've done enough math with this post today)
In that case the damage will become something like this :
4488-10156 *2 = 8976-20312
while plasma stream will deal
(9819-19743) + (4982-11318) = 14810 - 31061
which once again plasma stream come out superior
well that's my 2c CMIIW
