First, you will NOT get 81 flashes in 30 minutes....ever. Unless you're a computer or have nothing to do whatsoever but hit flash again the MOMENT it becomes available again, it will be far less than this. This is the trouble with people that rely TOO HEAVILY on equasions. The math gets you the information you need to make an informed decision. The point I was making between additional recasts isn't about laziness, it's about practicality. You're GOING to miss your recasts by a second or two occasionally because you're involved in other things or stunned or terrored or paralyzed or....you get the picture. My point is, that if I can get the same enmity for less actions, I'll take less actions anyday.
You are obviously missing the point about what I said about math doing one thing and the player base affecting that maths outcome......
Like my example, mathimatically you get that many flashes in that amount of time(@drac,the amount of time was used for example), no where did I say you were going to do that, but mathimatically thats your possibilities. How close you come to that possibility is all up to your player aggression. If you are off a few seconds each flash, it doesnt make haste any less appealing. You use haste for flash for 2 reasons. To have flash available as fast as possible and to produce more flashes over the course of time.
If you arent spamming flash as soon as its up and missing a few seconds, chances are its going to happen with either build and over all the haste build should be equal if not better than enmity b/c if you were pumping out more flashes with haste build you still will, but even thats up in the wind. Since time is the unknown for the most part you wont be able to tell whether you're going to get more flashes in or not, just an educated guess.
Here Ill show you a better example, hopefully youll see what Im trying to imply.
Lets say 15 minutes, thats a good time. Now rather than saying 50% haste vs 100 enmity because thats not a good example, well use a more down to earth example. Well use a setup that has 35 enmity(common flash build)with haste setup of 15%(50%) which is the norm under marches. Vs swapping a piece out for more enmity, lets say swift for trance. That puts the next set to 39 enmity with 11(46%) haste.
Now you can get about 40 flashes(vs 37) under 15minutes but we arent human and were bound to be a little slow on a few flashes here and there. So lets assume were like averaging out to be 3 seconds slow on casting our flashes when the timer is up. Meaning that would be 25 seconds(36flashes) and 27(33flashes) seconds on the other. The enmity produced would be 8748 vs 8250 nothing changed, haste is still better even if you arent on the ball with flashes. Reason being, regardless of how much haste you have or dont, you are still going to be playing in the same manner with either build. Now you might say, ya but I draw the line at blitz vs mermaid. Same thing, plug it in to this situation and youll still get 1-2 more flashes out of 1% haste over the other. This is not to say you "should" use blitz ring coz omgurdoing it wrong, its just its better in most situations when uncapped. Will it be noticeable? Probably not, but neither will all that access enmity you use for flash/cures when you're pushing cap most of the time after 4-5minutes.
You can bring up w/e variables you want, but regardless, what affects one set of gear will affect the other aswell. How it affects the gear you dont know because you cant control outside interferrance.
----> 5% giving either -3 or -2 seconds;
----> 4% giving either -2 or -1 seconds;
----> 3% giving either -2 or -1 seconds;
----> 2% may give -1 or have no effect;
----> 1% may give -1 or have no effect
Agreed^ I actually mapped out my whole haste percentages so I always knew if I was getting the full benefit from the haste or not. Basically depending on the amount of haste and the amount of the recast, it will either round off to shave 1 seconds off, or not. This is usually in situations where you dont have a brd, or only have 1 song, where youd be debating what piece to chose over the other.
Im not disagreeing with you Hellbringerx I just think you are discrediting how useful even a small increement(sp) in haste can be provided as Rya pointed it out you get that benefit. I think I posted that months/years ago when this was debated(when hasnt it...). Really the only real factor against even 1 second off flash vs more enmity is basically time. Since time is the unknown factor the majority of the time and doesnt come in perfect minutes/seconds. We just have to go based on what we can simulate.
In the end wear w/e you feel comfortable with, I personally like playing aggressive and from the /recast "<insert spell>" in my macro Im usually hitting my flash about 2-3 seconds before its up, just because all I do is tank, so for me I feel that I can benefit from any seconds I can shave off my flash.
