I dont like martials in 5th. I like having options. I do t care which class or combo or multiclass has the best power levels or damage outputs. What I like is having fun with 15 different choices I can pick from every round.
Here is also a little story. You know how you kill a demiliche easily ? Telekinesis to immobilize them. They have -5 strenght. And it doesnt do a single point of damage. But once they are immobilised, they are fucked since they have almost nothing long range.
Sometimes power level is small talk when you accidently jam your finger right into a boss's weakness and exploit it.
And the best part ? One time, a martial did something like that to a boss.
Damage dice are small. Weaknesses are all the rage.
