I'm really big on a lore, personally and I was looking forward to the Ebonhawke DRM because it was and will likely be the only engaging content regarding Ebonhawke in the coming years. Bangar's actions should have been a major a risk to the treaty, to which was acknowledged with dialogue from Smodur at the end of Bound by Blood. With the significant story changes for the leadership of the charr (sans Malice). There should be at the very least some dialogue about renegotiations or discussion of doing so once Primordus and Jormag are dealt with, at the very least. Not only do we not get that but we have Crecia pretty much stomping on the treaty with a statement of 'we all need to do better.' That is the most narrow minded, terrible view from someone who is meant to be a leader I've ever seen.
I take some offense to this idea that hundreds of years of conflict and loss and suppression on those of Ebonhawke can be hand waved after 9-10 years of peace. It takes at least a lifetime for things like that to heal. We don't have anything in the maps to signify how Ebonhawke has been able to expand or grow. Why does the DRMs have to be this poorly created instance, with in this case nothing significant other than Crecia and Kas (of all people) discussing the treaty only to toss it a side and be like 'the people just need to get over it.' What about Duke Samuelsson? Is there no one to actually speak for Ebonhawke itself anymore?
So onto the inconsistency, it's been mentioned at least once by the commander that it's been ten years. First of all the game is only NINE years old. If you play the personal story and run around field of ruins there is negotiations going on between charr and humans to discuss the ceasefire. Which takes place at the time the game launches. A ceasefire is NOT a treaty. A ceasefire is mutual agreement to stop violence so discussions can happen. A treaty is a concluded and formally ratified agreement. They just happened to toss that the formal treaty was ratified low key some years after the game launched. Exactly when and the extent of those details we don't know. So to say the treaty is ten years old is incorrect to their own lore.
I'm not a fan of the DRM content or the way they are ending icebrood Saga but this was salt in the wound.
