D&D General Mike Mearls says control spells are ruining 5th Edition

[mamba]

The gun doesn't get 4 iterative attacks. The user does.

yes, but the chance of misfire is for the gun. You use it more, you misfire more

A PF1e gunslinger who is supremely skilled (level 16+) makes four attacks per Full Attack, because they are extremely skilled with gunslinging.

As a result of this thing--arising out of their skill with gunslinging--they now encounter dozens of misfires every day. They are in no way even slightly better at preventing misfire than they were when they first trained to use a gun.

yes, because the chance of misfire is tied to the gun, not their skill level

Same as rolling a 1 on a d20, the more often you roll, the more often it will come up, even though you get more skilled with your sword or whatever
