If u start the math here you shouldnt do it with damage per second but rather with total damage. This means a rats-tail full of implications and stuff that can and might go differend. Im lazy, but not that lazy that Id build an argument on a calculation that is itself just a guess.
The fight doesnt only go 4 sec in which you have to maximize your dps. Its true that this kind of miximizing is basicly what a ranger is about but its not THAT straight forward. While in practice its still easy when you pick the strongest CA out of what you got available in theory it looks alot more complex imo:
U got tons of CA to choose from each round of AA but u naturally pick the one with the highest damage ratio... thus u prioritze Bloody Reminder over Jolting, Kunark over Immobilizing, triple over snaring etc. Im not here to state the obvious, rather Id like to show what result you get from this selection: when the strong ones are gone u pick weaker ones and when those are gone you go down in your list of priorities even further. A decend ranger builds his output around what gives him the most dps, staring with AAs (timing) and then ranged CAs/bloody/kunark. But at one point when those are used you go on with what Im gona call "fillers" now in this post: stuff like jolting, bladed opening, PBS etc... shit that u press when everything else is down.
Now your theory is right if I assume that u always got some high hitting (melee) CAs up that provide some decend spike damage, but it doesnt seem right anymore when you consider that, with this list in your head i mentioned above, the CA your gona miss out on during the last 4 secs of FA wer discussing is
always the weakest ones in your repertoire. Simply because you can build your output around it and therefor replace any potential loss with what youd otherwise use as fillers. Even by your math (which i dont agree with) and your own parse (
http://www.eq2flames.com/rangers/265...n-zones-2.html) you would not even get those 4k damage in between AAs.
Its pretty much the same logic as with an assassin/swash/brig who hardly loses any dps when jousting, just because he knows how to efficiently "miss out" on the weak CAs and, instead, spikes his stuff in the time he has. Just in this case you replace it for an enhanced AA, get the strong stuff in a few secs later and miss out on some fillers at any time to come.
However, and ill give u that, this might not hold true anymore when your equipment is extremely good. Pre RoK (and i excuse myself for not knowing to much about the time after) the use of FA was "make or break" your dps: with little self buffed dps and a base crit rate of 30-35% FA did a shitload to our AAs that, imo, was foolish to miss out on in any possible scenario. While I think that for most rangers this rule applies even now, Im happy to go with it if high end rangers tell me its differend (for them).
