During C4 disconnections at bosses like Baium,Antharas were fixed. Only not fixed boss was Valakas (was stated by Mystril). Now with latest patches when you dc at baium (confirmed yesterday) or at Antharas (confirmed by other ally) you ended in town. Could it be bug or it "fixed" with last patch. With increased difficulty of such bosses such dc policy hurts too much for any ally that try it.
It was first like it's now (reconnect in town). Then it was changed for Baium/Antharas (reconnect at same place if reconnected in 30 minutes) Then Valakas was introduced and there were complains why it's not same way like Baium and Antharas. Mistrill told that Valakas is special and it not a bug for Valakas. Keep in mind that at that point Baium/Antharas both offer reconnection. Then comes C5 and still Baium/Antharas both offer reconnections (we reconnected during our last raid for Baium). In patch notes only mention that reconnect at Frintessa (what-ever-it-called) ended in town. And last week they changed reconnection policy for Baium/Antharas. Without ANY patch notes or whatever information. At this moment it should be considered as a BUG because it's changed opposite to latest patch notes for this topic.
I'm ok with changes in game that are in patch notes. But some changes that affect a lot not in patch notes or not mentioned in any form by NCSOFT US.
PS. And with current difficulty of bosses like Antharas/Valakas/Frintessa it's stange to enforce such strong policy on disconnection. Like Antharas/Valakas/Frintessa raids could take 4+ hours and with less hp left these mobs stats (like hp regen) only increasing, while people continue disconnecting (for different reasons, including not very stable game client). It means that damage output of raid troops decreased overtime. It's not possible to get in such places if raids starts.
Its weird, according to game 'tips' at loading this is a feature, however a GM told someone on Bartz that its a bug (the GM was spam too, assuming its the same head honcho, he should know best so I hope he's right... I guess)
