Dragon Age Inquisition gameplay frustration

@F3AR_Combat; Some of your observations are valid, like the lack of a displayed value for inventory items unless engaged with a store.  But others are non-issues, at least when playing with k+m on a PC.

Either you are using a controller, (in which case I cannot help you) or you have not read/followed the manual/tutorials well enough.

For example: to swap equipment you can just double-click on the new item in your inventory, and the command for the entire party to follow the leader, or attack a specific target, can be a click+key-combination. Similarly, changing the camera POV in combat is a simple click-hold with mouse-spin.

The differences in AI tactics and movement mechanics from the previous DA games are mostly due to the switch of the game engine to Frostbite, which was originally developed just for FPS games. EA has mandated Frostbite for all of its AAA games for several reasons.  One is "they already own it", and another is that Frostbite allows very easy porting of a game between all three major platforms.
