If you look at the frame data the discord community has been compiling, Force definitely comes out on the lower (lowest?) end of the DPS charts:
Even Techer surpasses it (Thanks to higher passive bonuses and Wand PAs exceeding tech damage), the main problem being that tech damage is low. Any other class spamming a single PA will typically break even or exceed even the most PP-intensive tech combos being executed perfectly, and any error results in that damage falling away sharply. Contrast Twin Dagger's Circling Buzzard Skip Action at 389 DPS (For 1 button press) Vs uGizonde+4uZonde+cGizonde clad combo for 273 DPS (6 button presses, forced melee ranged and requires target is lightning weak)
What Force does have going for them is that they tend to be very good at staying on target and attacking constantly, where a fighter may have to reposition, or a ranger or gunner has to use their evasive skills, a Force with a Rod can guard and counter the attack without even breaking their casting and keep on blasting.
But that doesn't make up the difference, Force is the underdog class right now:
- Lowest DPS on paper
- Lowest HP/Armour pool
- Less utility than a Techer
They're super fun to play though, which is why I'm Force main and don't really care about the metrics; and besides, given the amount I seem to hold aggro on a boss in random PUGS, it seems like if you learn to play Force well you'll still out-perform the average rando spamming Julien Dance. But that doesn't make up for it either because if you put the same effort into say, Fighter. The difference would be drastic.
My guess is like PSO2, it'll be a late bloomer as they add new techs
