Felt that way with Morrigan, much preferred the friendship path than the romance one with her, gave me more feels.
Also it is impossible to complete a playthrough not romancing Lels, Maker I tried, stupid sexy red. 
Same here. I prefer Morrigan as a friend than a lover. Her seeing the Warden as a sister is the first hint at how much she craves familial love. Notice how protective she gets of Kieran, never once thinking about herself when she wants to protect him from Flemeth. That's a far cry from the 'always look out for number one' attitude she preaches.
Ideally for me, Leliana and the Warden are together, the Warden and Morrigan are like sisters, Alistair had a baby with Morrigan and the Warden (Cousland) married Alistair.
Which means that the Warden and Leliana are honorary aunts to Kieran and Alistair, the Warden and Leliana are my OT3.
Courtier: You share your mistress with your husband?
Cousland: No. I share my husband with my mistress. Nuance.
