Well actually with increased skill speed going from 1000 to 0 is less attacks. Every 3 seconds you recover 60 tp. So if at 4 minutes you use all your tp then you just used 5800 tp (1000base + 4800[ 4min= 240secs ÷ 3 sec x 60tp per tick] excluding invig cause it doesn't affect the point I'm making) vs 4600 in only 3 minutes. Now if the monk sits there tp starved until 4 minutes then he did the same amount of attacks and damage and what was the point of using selene at all then.
the bard has to be willing to play paeon when needed to make it a dps increase or the boss/enemy needs to die before tp is depleted. Almost forgot, or use to help with a dps check/push a phase.

Long story short, your getting in more attacks in less time which means in that time you have gained less natural tp ticks, so less tp to use overall

1. You cannot compare 4 minutes of no haste to only 3 minutes haste they are two different amount of times.
2. Underlined bit, that is point that is being made contrary to those claiming it is a dps loss when it isn't.

What PBC (PandaBearCat) is saying is that since your most TP efficient abilities tend to be DoTs of fixed durations that aren't impacted by haste, as your haste increases these abilities become smaller proportions of your damage. This is fine if you don't run out of TP, because you are still using them as often as possible. However, if you DO run out of TP and have to delay them to wait for a TP tick, you are losing damage that you wouldn't be if you hadn't TP starved yourself. Theoretically this shouldn't happen (because you can just slow your pace down to your unhasted levels), but if you hit a button every time you can and as a result run out of TP, it's a possibility.

DpCT is short for Damage per Cast Time. It's how much damage something does versus how long it takes to execute. Holy (200 potency) does more damage than Stone II (170 potency) to a single target, but because Holy takes 20% longer to cast and only does about 17% more damage, it's less DpCT to a single target. (This is just an example because I know the potency and cast times off the top of my head, please don't Holy single targets without a damn good reason) For any ability which is instant but on the GCD, you use your GCD as the cast time, because that's how long it locks you out of doing other stuff. There's a little more nuance in here for off GCDs and abilities which animation lock you, but the basic idea is damage per time spent executing. It's not quite the same as DPS because some abilities - DoTs - have way better DpCT than they do DPS. If I do 1 damage per potency, and a DoT does 300 potency over 10 seconds, it's only 30 DPS but 300 DpCT.

DpTP is much simpler. It's just damage per TP spent. An attack that does 200 damage for 100 TP has better DpTP than one that does 400 damage for 400 TP.

Yes, DoTs and DoT heavy classes(BRD/SMN/NIN) are the exception to the rule and I concede to that fact since Dot are not affected by SkS/SpS and therefore not affected by haste until the expansion. But for your specific example:

With poisons and slashing debuffs applied

Mutilate: 5.490/tp <-
Shadow Fang: 5.769/tp
Aeolian Edge: 5.202/tp <-
Dancing Edge: 5.032/tp

You can substitute those 2 mutilates for 1 Aeolian Edge Combo and lose a whopping 5 whole percent for that that amount of 170 tp spent.
