I've played DA:O at least 6 times and I staunchly disagree that it's a better RPG and a better game than DA:I. It was amazing for the time and I loved it back in 2009, but I don't think you could pay me to go through it again.
Edit: just realized you played it for the FIRST time. I guess in that context it'd come down to preference, but still. There was some janky and questionable design choices in Origins. You couldn't respec. There was no personalization (i.e., one camp site no matter where you were in the world). Crafting was odd and cumbersome. You always needed to have a mage as a healer, especially on higher difficulties. Not to mention the awful graphics. I had to mod it like crazy. I think I even found a mod that straight up allowed me to skip most of the Circle Tower and the Fade.
Oh and let's not forget: Give gifts for sex.
So wait, you hated the game, but played it 6 times? 6 playthroughs?
And yes, when someone says he prefers Origins to Inquisition, it's a matter of preference... and it doesn't matter the context, or that it was his first playthrough, I'm playing Inquisition on hard with friendly fire on, and going on 140 hours on just one playthrough that I haven't finished, I'm loving it, and I STILL prefer Origins.
So you say there was no personalization in Origins? You could build loads of different specs on it, especially as a mage. Here you're only talking about the looks of your base, not variety of builds or gameplay.
In this game you only have the illusion of variety. For a decent working build you'll be spamming Barrier most of the time, then you'll have enough mana for 1 more spell then wait for cds and use the same spells again, you rarely get to use more then 2 or 3 different spells in a fight cause of this. Also, you could call this mage's mana something like "blue action bar" since it's also only 100 mana, and you don't get more than that... and then you still have to go through and choose several spells you won't get to use because you can only have 8 spells to use at a time.
Crafting in Inquisition is still odd and even more cumbersome than Origins, making it even worse due to the crappy console port user interface that PC gamers get stuck with.
You say you had to use at least one mage as a healer? here you still have to have every single one of your mages have the barrier spell, but lets talk about healing then.
No healing spells or healers creates better fights? in what way, you'll still have to use at least a mage on a decent difficulty, you'll spam pots FREE health pots or spam revive downed followers, by a "healer" spell or by having any of your followers run up to the corpse and revive him in 5 seconds. Currently I'm playing on hard with friendly fire on, hand have 12 free shared health pots that can be spammed, followed by 20 health regen pots that cost 1 common plant each and 12 AoE grenade heals than cost nothing as well.
Lets also not talk about god mode specs such as the unkillable Knight Enchanter that can solo pretty much everything while being under lvl for it.
Awful graphics? in 2009 Origins didn't look that bad and at least it was modable. Inquisition according to the developers, doesn't have their support, and is also very hard to do without support, especially since its frostbite.
