Lies. The only ally we can't get rid of is the Alister. All others are optional, you can refuse to accept Lelliana's offer, you could miss Sten if you haven't persuade him to join you. You can kill Wynn and piss off Morrigan (via camp talk or in the Mage's Tower), you can reject Oghren, you can kill Zevran...
Srsly, how about you learn a bit of subj before join to the convo discuss? Being ignorant and using exaggeration to support your point leads convo to nothing.
As the ultimate statement related to the thread's subj: D2 has NO choice at all. You even can't kill Talana instead of accepting her powers. But there is such (similar) option in the dialog! Meh...
Are you deliberately failing at reading comprehension or are you just blinded by fanboy raeg? Your condescending attitude in this in other threads is as always hilarious.
Allies = golems or Dwarves, Dalish Elves or Werewolves, mages or Templars, NOT party members. The whole point of the game is gathering allies to smite the evil hordes.
"D2 has no choice at all" is also false. Take for example the quest with the letter of the farmer's wife and the quest where you must choose your trainer.
Anyway, you're right though. Discussing something with the likes of you leads to nowhere.
