aight having too much skillspeed isn't as detrimental in raid environment as dummy since I don't think there's any fight where you're using optimum 3 laser/min timings

i got 711 skillspeed on my current set and I don't notice my self losing lasers due to skillspeed since we're inherently delaying them for mechanics

i don't really hit anything from the front that much in a4s so I might just stick with the 639 set but I'll probably go for the high crit low det set first as I prefer more skillspeed as a buffer for things and 650 sounds more legit to me than 604.
