You still don't get that that was entirely caused by players?
No I don't. And that's because, especially in the case of D'Hara, a reason was never made apparent. One day we were getting along with them cordially and they had ambassadors visiting us, the next they marched silently into our lands, ignored attempts to engage in RP (completely different to their previous reactions) and just looted and burnt the !@#$ out of everything.
We never found out why they did it, why they changed or even got a good bit of RP out of it. GM controlled factions are meant to be there to make the game interesting - if they come to a player realm and then don't even engage in the slightest bit of RP interaction then what's the point of them? For that matter, why is there this sudden change in the Zuma lands as well? Originally they RPd them as having substantial populations and a bustling city and now if you visit all you get is silence and, if you're very lucky, the odd RP saying that no one is to be seen.
There is no consistency nor consistent inconsistency. And that just sucks the fun right out of the whole thing of them being there. We could replace them with a monster horde for all they contributed to the game experience.
