Don't make too much sense.
I think DAI's combat is the best as well, though I like playing as a mage the most in DA2. The elemental tree was a lot of fun for me, since I always gravitate towards a fire or frost mage in most games when I play a mage. Having fire and frost as separate trees feels a bit unnecessary to me, and I'm not too keen on the pruning of most DPS abilities from the frost tree. It's too much CC and utility for my tastes, I like to make things go boom. 2H warrior is leagues better in DAI than in DA2.
Origins combat is so painfully boring for me. It's too slow for me to call Origins an action-RPG, but it's not turn-based and can be played in real-time. I've tried the "pause and issue orders ever few actions" way of playing, and I don't like it for DAO at all. Same as when I tried it with KotOR. It works better for isometric cRPGs, IMO, where you have a view of the entire battlefield and can play it like a miniature RTS. Not to mention that Origins combat is so passive. Literally you can click on an enemy to initiate combat and your allies will kill everything for you. The game plays itself, assuming you don't have turned up to the max difficulty. Just keep Taunt and War Cry on auto-cast for Alistair (or whoever you have tanking) and keep Tempest and Firestorm handy on Morrigan (or whoever is your party's mage) and it's gg.
A lot of "educated" people I've met say the most ignorant things or think their education puts them above others, and it oftentimes makes them closeminded. In other words, where Einstein sees what he still doesn't know, a lot of people that value what they learned so much in college sees the world within that snowglobe, the scope of what they know alone because they think its enough. I.E., education often leads to arrogance.
To be honest, with the right build, DAO still basically plays itself on nightmare. The ai doesn't get any smarter and the system is easy to abuse. Harder than Inquisition though by far, but not because it's better. Just more frustrating and slow.
I mainly played as a mage and rogue in DA 2. DAI is the only one of the three so far that I didn't much care for mages or rogues. The armor has a large part to do with this honestly.
