Well, that's more an issue of timing, most of all. If Lolorito dropped the act when Raubahn killed Teledji, Raubahn would have probably still made a beeline for him before he could explain that the Sultana wasn't really dead (probably along the lines of: "You manipulative bastard! Are we all chess pieces in your little money grabbing game?"), Ilberd would still have faced off against Raubahn (since Ilberd's main issue is that he's really butthurt about Ala Mhigo). And, for us players, it took months between the end of ARR and the beggining of Heavensward but, really, only a few days to maybe a couple of weeks passed between that, and even a few days before that other event.

Could it have been handled better? Sure. Is that plotline over and dealt with? Abso-freaking-lutely not, and I'm really expecting it to continue through 3.x along with all the OTHER plotlines 3.0 opened up.
