Not getting the triple attack argument. I'm giving Epona's a better-than-actual test by assuming EVERY hit in the 3 hit CDC will produce a triple attack. Since you can't get TA and DA to proc both at once, I don't see why I need to account for DA at all when it will give inferior results.
That is exactly why people like to know whether things have good or bad returns when stacked. DA/TA have diminishing returns so in fact, the increase in damage from Epona's will be even less than stated in the calculations if you have any sort of DA/TA. DEX crit hit rate increases are small when dDEX is small, but increases in an exponential way when dDEX is large (there was a nice graph on this on BG several months ago). In that way, stacking DEX would be even more beneficial in a way I haven't even tested by the added crit hit rate (moot point if rate is capped, plausible in abyssea). Point is, if you have Person A with a CDC set which includes Eponas and Person B with the same set but substituting Eponas for DEX+7 ring, Person B will, over time, deal more damage.
EDIT: Did some background reading on past threads on BG like
http://www.bluegartr.com/threads/838...-Triple-Attack - which some people say DA/TA can only proc on the FIRST hit of a WS and the offhand (when dual wielding). If so, this does not look good for Epona's since my calculations assume all hits triple.
By all means, please work out the maths to prove the counter-argument. It would be nice to not have to lug a DEX+7 ring around so I wouldn't mind.
