Many things in DAI was not make sense if not stupid, and many companions of our Inquisitor not make sense as Inquisitor companions at all, only as agents but no more....companions was mean to be our main circle, people who have power and ifluence, who represent some major and valuable groups not a random peoples from streets.
i am not understand why we do not have option to punish-execute them(exсept only Blackwall what would be executed not by us and not because of our choice to execute him) because in many situation we have any right to do this, but still we cant
Vivienne-noone who represent herself only, and some ultra loyal pro Chantry mages, it was make more sense to have Fiona or someone else from rebelion mages who join to us.
Dorian-(he especially was not make sense on templars path)exile from tevinter, who even was never a magister, the whole situations with him especially his "drama", was pathetic and not make sense, it was outplay
Blackwall-we hire him as a high ranking officer of grey wardens but for nothing, he does not give anything for us and he is no warden(what was too obvious from the beginning and look stupid considerate our spies) at all, and was a simple killer....it was make sense if we have a Stroud or other warden officer as companion
Sera-she is no one, have nothing useful, and she is even act to us like we are some peasant buddy
Cole-weak crazy demon without any use, and with mindless and lore breaker powers who work on Seeker Cassandra, Solas and Inquisitor, especially in place like Skyhold for no reason
Even from our advisors exept only Leliana who was a Orlais Chantry Divine hand(but we have devs promise that our organisations will not be connected to Orlais Chantry, so she and Cassandra is no use for us and as with herald of andraste title....it was understandable if the have them when we was a pro CHantry and Templars Inquisitor) was make sense
Cullen as a "Kirkwall hero" and our military advisor, and general is a joke considerate who he was, what he is doing as and what he was done...he do nothing good and nothing right and he was a dumb and weak warrior and especially as an officer....he was retconed as a Anders from DAO-A.
Josephine is just Lelianna friend so this is the same as with Lellianna, anyone especially varrick make more sense to do her mostly useless job
we was just forced to do many things and have some people, mostly for nothing except to watch hear and sense their own atmosphere? it was make more sense for DA2 with hawke in city but sure not in DAI about Inquisition and real problems
