At most I swear and scream at the quest givers, especially the ebonheart pact. Nords asking me to kill and set their loved ones free to soverngarde enlists the most illicit curse words I have screamed at an MMO. How about others out there?
Myself I beg for a just a decision in there in which I unleash unlimited power and drink in their screams and terror as I murder them. Especially the nord quest givers for me at the moment. There constant yammering about loved ones and soverngarde makes me want to massacre the whole lot of them and raise them as undead servants and get them to solve their own problems. I would gladly give up my meager XP and quest reward just for that decision.
Even if it gave me a bad rep, soldiers would realize that asking me for stupid favor to complete their quest would result in turning them into an undead abomination to complete it. I guess thats my minor grib, if SWTOR I love going dark side against someone so stupid that I would make an example of them.
