So, I held off posting this a bit in the hopes that the hydrostatic podcast would hold some revelations that would change my opinion. So far, no luck - so here goes.
Issue #1: The cascading negation of storylines.
Simply put, killing Jamyl negates a lot of other ongoing storylines. The clone/not-a-clone debate appears to be at an end for one, but more importantly 4/5 of the heirs are going to have to die. That's a lot of characters to purge at once, and a lot of storylines abruptly dead-ended. Catiz' shenanigans with Khanid? Articio's turnaround? Ardishapur's excellent chessmaster handling? Come tournament completion, 80% of those excellent storylines are going to have to end.
And... for what? Shock value? Getting rid of a character some people didn't like, because they'd been written badly in some cases? That's a lot of collateral damage for what could have been done with a much smaller impact. Worse yet, it was abundantly clear from news stories and chronicles both that Jamyl was not an unsalvageable character - she just needed to be written reasonably well enough.
Understand, this isn't purely an Amarr issue either. It was an issue when CCP dropped a Sansha-themed hammer on Heth's head instead of having the State catch him, and it was an issue when Midular was abruptly killed and seemingly brought an end to the Minmatar cooperate-or-fight divide.
Overuse of 'shock' and 'epic' tropes.
It's been said elsewhere, but I think it bears repeating: If you pound a button long enough, that button becomes broken. CCP's been pounding the 'epic' button for several years now, and it's pretty much shattered into a thousand pieces by now. I can't go 'OMG, the empress is dead' when how I really feel is 'Well, the empress is dead. Again. And the last emperor too. And the guy before him. And a good half-dozen other heads of state in recent times.'
Simply put, SHOCKING BIG DRAMATIC DEVELOPMENTS have become the norm... at which point I can no longer enjoy the shock of them.
You know what would have been truly impressive, but lacked the problematic storyline issues in the first point? Have the Drifters blow up the station. We've been conditioned to accept stations as immovable, indestructable monoliths of EVE topography. CCP's wanting to shake that up with Citadels, so why not have them start off by nuking that station to begin with?
Use of pre-programmed AI as an excuse
This is more of a minor quibble compared to the other stuff, CCP have repeatedly claimed that they "did not control the Drifters" at the event, that they were "entirely run by AI" - and that as a result, Jamyl's death shouldn't be considered "dev intervention". I really don't think that counts as an excuse - if you code it so that they blap and warp off immediately on firing, so you only have to /spawn a huge number of them and sit back, you are still directing the situation.
For that matter, I will be frankly shocked if we ever see the point where Drifters display this same behavior against player-owned titans.
