If you look issolated on the career builder then sure BW is stronger than Sorc for aoeing. And yes Rain of Fire will deal more damage than a Pit of shade.
The realms are balanced with synergy and two different playstyles.
Order as a whole has the theme of ranged knockdowns, raw damage and +healing.
Where as Destro have the snares, the incoming 25%healing debuff aura (vs 25% outgoing on knight) and more of a largescale utility and displacement advantage to break these Order-clumbs.
Rain of Fire being increased from 20feet to +50% is nice and handy.. Versus pugs.. Any organized 2-2-2 warband will mitigate your damage with a M4 routation and then you are playing with one less tactic on (want this arguement used further up in this topic about sorc and aoe punt on PoS?) But sure, the pugs will die in dozins if you have a guard+heals to mitigate Funnelpower when you hit 24 players with RoF.
The Ranged knockdown will consume your Ignite dot, which is your own source of resist debuff. Two GCD and consuming a tacticslot, or you not running with resist debuff.
Backdraft is personally my favorit build, not the best, but my favorit. it gives me a tool to escape if i get pulled by a choppa, magus, or mara. As I dont have a disarm to deal with getting caught.
Flashfire change/buff came out of nowhere, and deep down as much as I love it. I dont think BW needed it. But here it is, bugged animation*** and pretty danm strong! For a class that only really has damage to offer, getting more damage available is nice. Most guildie BWs and pug bws ive seen in city, dont get enough value out of their flashfire procs and it shows on their damage done. So either they run it but not optimally or they slot something more forgiving. The tactic gives me flexibility to assist with criticalmass and singletarget on low/priority targets and in general just boost how rewarding a "3 ability class is".
In the end of the day, endgame gear is here and bw/sorc are pushed further and further in the back for endgame content like 6v6 ranked and cityinstances, and melee + singletarget frontloaded burst+mobility is taking over. These casters are still good for pugstomping, and anyone who followed the Live citysiege meta kinda expected this shift to happen eventually on here.
So IF or WHEN instant aoe morales are nerfed/tuned down I think it might be the end of the BW era for good, and im kinda hoping it will happen soon as I am "burnt" out with morales
*** Flashfire patchnote stated that the animation would get fixxed later on, it is still not fixxed. And if we are following the logic on Why Engineer Electromagnet pull was reverted back to having a 1sec delay vs magus 0sec delay, simply to not **** up the engineer animation, then I really dont know what to think.
