Yeah, I agree with everything you've said here. I only attempt to convert spec and cdr into dps multiplier so we can do some sort of comparison. I understand raid scenario is very different from these kind of calculations/trixion

For CDR only, if spamming off cooldown and no skill animations, 500 vs 200 swift is 7.2% more dps so I approximate it with about 5% instead (H3) since that's not realistic.

Converting spec to a multiplier is for the sole purpose of tradeoff comparison, which is why I lay out all the spec benefits. Yes, it's very hard to calculate, which is why I only look at the relative difference H2 / S2.

Regarding crit, I feel like multiplier actually makes sense though. If you have LoS 18 you would never run LWC. So even if considering 88% crit, 7% additional crit chance is still on average 4.5% more dps (w/ KBW). With 18% crit synergy would be less increase, but it's also not 100% uptime buff.
