Yup as Warkitten stated, you can try different builds to see what you like, and over the years I have tried many set ups, on live had a 90 sorc, and a 96 BW, here I have been away for a year or so but still have a 80 + BW. and a 40 sorc I haven`t leveled since march 2016.
For single target Scenario type build, I1d focus on something like this the heal debuff is ok, but it will normally be covered by a melee class, this allows you to set up burst rotation, with witherhing heat, and FBB to assist on kills, you could go Stop drop and roll instead of FBB,

For the AOE build, nothing wrong with backdraft, but has limited use as can knock players away, and give immunity, I tend to switch between this build in open RvR

And this one for city if I do city, haven`t needed to do city in 2 years, but this one does ok provided you have guard as it requires close combat. and you will be focused.

If no guard bot and deciated heals, use a set up similar to the other, Fbb, nova etc, with ruin and dest as moral 2 . for moral bomb . for a more ranged aoe build,

Wounds are important, you want to try and get to 8000 + unbuffed so with wp hp buff you`ll be around 9k to survive moral bomb, and then itel as close to cap as you can, mix and match sets to get stats you are missing, I normally am around 1040 intel, 8500 wounds, and with combustion, sets etc 75% chance to crit.
