In retrospect, mastering a new difficult engine, creating big zones and trying to apply all of this to 5 different gaming platforms was not probably a good idea. Each of these tasks is challenging on their own, all of them together...
My main problems with PC controls and UI.
1. Hitboxes (on big models, mostly). When melee characters can't reach enemy and hit empty air or slowly strife around to hit them. And good luck hitting someone lying on the ground. I thought to create all melee party before release. Nope.
2. Tactical mode. A lot was said about it: not working in dungeons, stucking in every little stone, invisible because trees. Only zoom was improved a bit so far. And sonar doesn't work in this mod.
3. Menus, especially inventory. Clumsy, awkward, frustrating. How come in previous games you could see all skill trees in one sodding screen, and now you can't see even one?! How come you have to go through all your companions and not just select the one you need? And crafting: you have to use 4 different interfaces and you can't even compare what you have at the moment with what you craft. And of course you have to list through all of your companions again.
4. Panelbar. 8 slots, really? To make the combat more actiony? And why stupid mount has its own button? I don't even use it, but I can't reassign it to something else.
5. Mouse, poor mouse. It's evolution is lost and forgotten.
6. Picking up loot in action mod. Stay 1 mm from it, can't pick it up, you are too far.
And that's just control and UI problems. There are also too short story drowned in the ocean of boring "bring me 5 elfroots" quests and collectibles; mediocre reused antagonist who was already killed in previous game DLC; bells and whistles (music and party banter not working, terrible hair and Skyhold outfit).
I don't think Inquisition is a worst game ever. It's a mediocre, average game.
Did it improve my opinion about the company which was shattered after DA2 and ME3? No, it made it worse. From "buy short after release" BioWare games moved to "maybe buy after huge discount" category.
I'm not going to complain how BioWare betrayed the trust of their PC audience and how amoral their PR campaign was. This is a language EA doesn't understand. So I'll just vote with my wallet, that's it. There are Pillars, Witcher and a lot of old good games.
I just want to thank people who participated in this thread trying to improve this game and experience for other players, especially patch testers.
