I never said I helped everyone. I helped people that are either beneficial to me to help, or whom helping does not reduce or risk my ability to fight.
Since you seem so "logical", you think 3 mages, 3 children and a crazy girl are a good exchange for 20 templars?, I hated how they made choices like "If you side with the mages, you win a new companion, if you side with the templars, you are a bastard, f*ck you"
That should be "You win Wynne with the Mages, you win Cullen/Other templar with the templars", of course you already have Alistair for templars, but if you are a magi warden you already have a warden.
First off, it's a hell of a lot more than 3 mages. Secondly, mages are a massive force multiplier. Thirdly, when you make the choice, there's no reason to think you won't also get Templar help. Hell, it makes very little sense that you don't get some templars along with the mages. Given all that just happened, there's no way they're sending mages off unescorted.
Uncontrollable? they are better than simply dalish elves, if you want to stop the blight, you prefer the elves of Santa Clous throwing arrows or werewolves?
The archers probably. Well trained archers are a significantly greater asset to an army than melee troops (see Crecy, Agincourt etc.), especially when the latters' ability to follow orders properly is suspect.
And excuse me if I don't believe you didn't do Morrigan's ritual.
The characters who consider Loghain a useful tool won't do the ritual. The entire concept of it is utterly crazy (Morrigan might claim it's safe but the hell I'm trusting her when it comes to preserving the soul of the thing causing the Blight) and I have someone ideal to make the sacrifice in my place anyway, so why take the risk?
As I said though, I have played other characters with other views, and one or two of them have done the ritual. But even among those who don't spare Loghain, most would rather see themselves die than risk letting the Old God's soul survive.
Loghain is a useful tool?, you lose Alistair, and if you have to choose between the whiny ***** who followed you the entire game or the traitor who tried to kill you the whole game, sold elves to Tevinter, let Howe do whatever he wanted, etc, the option is clear.
Yep, it is clear. You take the highly experienced soldier and exceptional tactician not the naive boy. If you really like Alastair, give him the throne. But bring Loghain along with you to stop the Blight - and if you think he must pay for his crimes, he can be the sacrifice that kills the archdemon.
