Looking at the new FT, it speaks volumes of the many goal that blizz has tied to it:
1) They wanted to keep an old name around for nostalgica's sake, and to have previous players not feel lost as much. FT was never a really engaging spell though, so thy're now trying to make it more interesting.
2) They want to emphasise the "enhance" aspect of enhancement, which is largely represented in the old imbues. WF was made interesting again with doomwinds, FT received this new look, and rockbiter was remade into something entirely different, just like FT, to satisfy point 1): keeping an old name around, but with a meaning.
3) They wanted to keep a maintenance spell in our toolkit after getting rid of FS and UE. Blizz didn't want to have the loss of FS/UE feel like it left a hole, they made FT like a mix of the two, plus it's own, older version. Blizz cleverly tied up several aspects that we grew used to into one ability that adds maintenance and fits our class theme.
Now, with all the praiseworthy aspects about this, there's points about the ability I am "meh"-ish about.
1) It is ~sort of~ a melee dot and passive damage, so it is barred of dealing all to big damage. It adds to the damage source count as well, contributing to the overall number extent limit of each ability. If we go the (almost) highest maintenance route for enh (which seems to also be the one with the highest output (windsong/landslide/?spiritual affinity?/FoA/Ascendence) plus artifact traits, including another maintenance spell may stretch it already.
I dont have access to alpha, so I cannot comment on how it feels though, gameplay-like.
But would it be an option to raise it's cooldown to a minute or 90s or something, and have it deal impressive damage during that time? Maybe be included in Crash Lightning if it isn't already?
Or instead of that, maybe remove it's cd and raise it's range to that of LB, and remove LB. That way, we'd share less with ele, retain a range pull, and have a QoL improvement as far as boss engagement goes (FT => GoT => start damage). The initial damage of FT strikes me as similar as LB's, and I find it a little irritating to keep LB on my bars just for the ocassional ranged pull.
2) I'm happy that CL (Chain Lightning) went away for the reason both wordup and I brought forward. We're a melee spec. CL is ele's tool and we've shared it long enough. I am not opposed to a new, unique to enh ability similar to it though, but designed with melee combat in mind. I would say something like forked lightning, dealing cone damage in front of us, but then I'd have to say Crash Lightning is essentially that, right?
If we we're to get an additional aoe ability, I'd hope for sundering maybe, as a base ability, but without the knockback, and dealing respective damage. Would look good to combine the lightning aspect of Crash Lightning with Sundering.
3) LS imo would be cool as an aoe-dps and/or survivability cooldown. There was that warrior ability I cant seem to remember or find on wow-head, which allowed for warriors to reflect damage back to the attacker (back in wotlk).If you used it with bladestorm against another warrior during bladestorm, you could get ridiculous results.
I imagine LS would be nice like that; a significant damage reflect cd. Imagine it in pvp. It would keep the essence of the spell, but put significance begind it. Would definately make it a pvp talent though.
The other approach would essentially be the road of Fury of Air. A strong ability that would prompt player attackers (melee) to seek distance/lay off you, while doubling as an aoe cd. That said, FoA does that already, though I cant shake the doubt the ability was conceived for utility (aoe snare) instead, and is supposed to deal 160% weapon damage in total, not every second. The other two abilities in the same tier are just that much weaker, and support my theory. You currently have no option but take FoA, but if it were minor damage-wise, while still consuming that MS, you'd only ever used it for the snare (if at all), freeing up the other two options.
