Eh, personally I found it very refreshing that the Warriors of Darkness had contempt towards the Scions and Warrior of Light. I've grown increasingly tired of all the hero worship surrounding the main cast though - especially since they're rarely in any real danger and we've suffered countless 'fake outs' ever since the end of 2.0 where death and injury is concerned. Yes, we lost Haurchefant and Ysayle back in 3.0 but even then they were secondary characters and it's crystal clear that the main Scions and City State leaders have firm plot armour to shield them from genuine and long lasting physical and political consequences. I wonder how many more times we'll be teased with the likes of Aymeric maybe dying but never really being in danger?
It rubs me the wrong way because it means that any new characters who are introduced to keep things fresh - such as Moenbryda or the Warriors of Darkness - end up being the ones to be killed off. Usually very abruptly too. I'll be honest and say that a lot of the major characters in this game bore me though. I'm not very fond of the likes of Cid or Aymeric. They're far too self righteous and without any real, meaningful flaws. I prefer characters with more depth and complexity to them - the sort of characters who screw up from time to time or can actually be selfish.
That's why Ysayle and the Warriors of Darkness worked for me. They screwed up, they had flaws but they weren't completely rotten and believed that their causes were just. I do wish more characters with flaws stuck around though.
Overall though the storytelling is still a lot better than what other MMO's offer. Hopefully 4.0 isn't afraid to go above and beyond 2.0 and 3.0. The developers do appear to take constructive feedback on board after all.
