Re: 4th Ed. Veteran looking for advice on 5E
Howdy!
We found 350 was a touch high, so we used 300 the first campaign we did by 5th Ed. Later we felt more confidant, so we went with 350. Like other folx here said, it leads more to rounding out characters than building combat monsters, less the GM don't have good control.
We ain't seen to much of "12d6 syndrome" though that usually is the strendgth of the most powerful attack. Course, with all the Advs, Lims, and SFX, they don't feel all that much like they're the same.
With 350 points, 'bout every character is faster than with 250. If'n the GM keeps combat monsters from happening, there's still a range of SPDs so it's all good.
