I prefer to run the Phoenix Adept this way ever since the Singularity change:
6/6/0/6/6Run a good set weapon and the Acolyte. Typhoon even works well, especially with Incendiary Ammo. What you can do is use Singularity to ragdoll basics, then fire on other enemies. For something like a Marauder, try firing till its sheilds are near gone, then hit him with singularity. He will get lifted on fire and you can ignore him as he will get killed via DOT.
For large enemies, use Singularity and abuse corners so you can Smash and set of BE's.
Phantoms are a laugh with this setup: fire Singularity and they go into "bubble" mode with the Singularity sitting on top of them. Fire the Acolyte to strip shields, and when they turn the bubble off they will get immediately lifted into the Singularity.
For the Vanguard I like something like this without Lash again:
6/6/0/6/6Since there is no Lash, I don't bother spec'ing Smash for combo detonations and go with the Electrical effect instead. You have more than 1000N of force on Chage so you should be able to stagger Phantoms. Chage, then you can go into heavy melee. Also learn to cancel out of the Smash animation into a roll or melee. If you think you need durability, you can consider going more shields on Fitness, but remember that you do have Charge.
