Maybe i should first explain my understanding of ascened gear (for the case of me having a misunderstanding). Ascended gear is gear to increase your stats further and give a new goal to keep player (farmer) in the game. But these things absolutly dont work out:
Not needed: I want ascended gear, but i am still working on my exotic gear and leveling my other charakters. My 80s are a Mesmer and a Ele, my Ele plays with the gear i found in TA (lvl55, green or yellow, i mean accessoires, backslot, trinket and rings), my mesmer has green lvl80 stuff. I know, that ascended gear would be better, but I have no problem without them, why would I be motivated to get them?
To hard to obtain: I am a casual player and dont like fractals. Also making daylies and monthlies, PvP and PvE each time kills a lot of time and has more of an obsession than joy, furthermore, casuals often play not soo much, only a few day in the month (hard to finish monthly) and then maybe only 1-2 hours (hard to finish daylies, especially, if you not concentrare only on them). It is already a time-eating process to get them for one players (at least even with the 100e, it is makeable), but not doable in a lifetime for all my alts. Also fractals are not easy and without playing non-stop fractals, you wont reach higher levels. The third option is the mystic forge (or do you need also here stuff out of FotM?) These recipes all need expensive, time intense stuff, nothing a casual can bring.
To easy to obtain: I meet non-casual players often enough. They play so much each day, they have not only to look after the daylies, they will get them anyway. Also the monthly in one day is possible for them. They also can play much time in fractals, it is far to easy for them to get full ascended gear and are know whining, cause they dont know, what to do with the dropped ascaneded gear they don not need. These are the players, you wished to keep busy, you failed.
Most effective players: There is a type of player, who farms only, plays only one profession, only has one armor and one weaponset (most likely expensive skins and Berserkerstats) and there is the type of players, who loves to have alts (I also aim for one Charakter for each profession), buys many stuff (I plan to have 2-4 armors with each of them and want to have at least each useable weapon for them once) and so need far, far more, furthermore there is the type, who likes to enjoy the game in a way without ingame rewards, watching the area, making RP, … You dont want to make stuff to easy to obtain, especially cause the first type only need few things. But the actual way is horrible, the first type still can get his equipment in no time, but the second type will never finish obtaing them and the third type will not only think about spending his important tme with stressful and boring farming.
Exotics to ascended For me, leveling my charakters and working on my exotic gear is fun. It takes a lot of time, but it is fun and is not too hard. I think I wont be finished with all my alts before the ascended weapons and armors come out, cause it consumes a lot of time. But what about ascended gear. Hmm, fractals are OK, but the levels make them unattractive to me as casual, I prefer dungeons. Laurels are annoying, of course I want them, but as a casual, not playing often, to get them by finishing the daylies keeps you from the things you really want to do. So i dont think, obtainig ascended gear is fun. Furthermore, i fear ascended weapons/armors. It would mean, all my earlier work was for nothing and cause it must be harder to obtain them, it surely wont be so much fun like obtaing exotics is…
Better stats for better players: Legendaries are the way, it should be! They have a special skin and need a lot of time to be obtained (but still not enough time). Ascended are not. They take a lot of time and are rather a standard only for the best players (type one). But the better gear makes them even stronger, increasing the gap.
