We came from having spells like Fireball, Drain Life, Crushing Prison etc., I found those spells useful.
And as I've stated above with the hair selection comparison, I'd choose more options any day over less options. Same goes for tactics, same goes for ability points, same goes for quickbar slots, and so on.
Ok, so now you're going to name 3 spells out of 80 that were usefull... and suddenly they are all usefull? Or are you saying that 3 great spells out of 80 is good enough?
And even if all 80 spells were usefull, 7* orso of them eclipse all others.
I'd choose more
equal options over less options too, but the options we got were far from equal. At least in DA:I all options are equally feasable, unlike DA:O where certain skill setups are not just a little bit better than others, but just downright game breakingly overpowered.
*Blizzard, Tempest, Earthquake, Inferno, Spell Might, Glyph of Paralysis, Glyph of Repulsion
Add Force Field, Walking Bomb and Virulent Walking Bomb and you have all the spells you need to faceroll the game. (for those who don't know: the Archdemon is very vulnerable to the Walking Bomb spells)
And I'm being really generous here. You could do without Inferno and Earthquake and you'd still faceroll the game.
