Games have rules for a reason. Not using an obviously effective mechanic doesn't feel like choosing your playstyle, it feels like shooting yourself in the foot to fix the gameplay.
There are two main problems to this:
- "a player can just not do it" is a shitty excuse for bad game balance
- a game is made up from mechanics and mechanics create a certain "gameplay type/environment" and a certain "feel/tone"; a grounded tactical game feels completely different from a game overloaded with explosions, ground effects and what have you; it also strains believability
Completely agree. Rules and restrictions MAKE the game. I want to play D&D with a DM telling me what I can and can't do. I don't want to be my own DM.
