Loghain MacTir of Denerim is one of the bad guys in Dragon Age: Origins that can join your party in pursuing the archdemon. We’ve seen how f*cked up he is when he abandoned King Cailan and the rest of the Grey Wardens in the fight to slay the darkspawn. Well, recruiting him is indeed worth it but it will ask for something to sacrifice; that is to kick Alistair out of your party.
After his defeat in the Landsmeet, spare his life and force him join and become a Grey Warden. Doing this will make Alistair leave the party. It’s really a hard choice; it’s either Loghain or Alistair. Let’s take a look on the base stats of each of them:
LOGHAIN’s BASE ATTRIBUTES
Can teach a “Champion” specialization.
ALISTAIR’s BASE ATTRIBUTES
Can teach a “Templar” specialization.
There you have it, it shows that Loghain has a lot advantage than Alistair. I prefer Alistair over Loghain but if you want to see something new, then go ahead and pick Loghain.Dragon Age: Origins - Truth about Recruiting Loghain,
