This is what's wrong with Dragon Age's PC controls, camera, and UI:
1) The #1 problem with the camera is that you cannot lock the camera behind your character. This results in constantly fighting the camera to point the direction you need it to be pointing - where your character is facing/looking. Every 3rd person perspective game I can think of (MMOs, RPGs, etc.) lock the camera behind your character by default, or at least give the option.
2) When you take your finger off the W key, you don't stop moving. You glide/skate for a while after. This is very disorienting and unrealistic. A living being is able to stop where they want to stop when they are walking or jogging. They don't glide to a stop or overshoot where they are trying to go (for the most part). Furthermore, it is frustrating as heck to deal with in a game.
3) The strafe keys don't really strafe. Your character turns and kinda glides a bit (see #2) and it is motion sickness inducing. Because of the camera not being locked behind your character, this is even worse.
4) When you hold down RMB to start controlling the camera, it immediately jerks the camera and your character significantly
It seems to treat wherever you hold down the RMB as if you held it in the middle of the screen and then moved it to that spot
Instead of every other 3rd person game on the planet that doesn't start moving the camera until AFTER you hold down RMB.
See this video:
5) No true lock on to targets. You have to manually follow them. This is particularly bad because of #1 through #4
6) Terrible lack of visual indicators of your current target. It is a very tiny + symbol in the middle of its body.
No circles on the ground. Nothing like normal.
7) You have to hold down LMB or R to keep attacking.
8) Only 8 ability slots. Terrible. Absolutely Terrible.
9) No ability to swap between ranged and melee weapons.
10) If you click on a lootable item from more than a few feet, nothing happens. Your character doesn't walk to it and pick it up.
11) Searching is horrendous. You have to spam V to search. It highlights items for a half second. Brutal.
12) In general, it is like they haven't played any MMO or 3rd person game from the last 10-15 years.
