could you, say, choose a timeline at level 47? And then stay in it till 49,
On my last ding to 48 I was in WoD timeline and the surrounding mobs remained level 47 (proper chromie level) when i dinged... but I didnt check to see if they remained that level once I left the zone/expansion. It was the same that chromie wouldnt talk to me, however, so
at best I was locked into WoD chromie time for the remainder of my pre-SL experience.
I didnt check anything else about it tho, but of note was that WoD treasure items I picked up off the ground at 47 showed on-screen that they were ilvl 52 or so when i looted them, but in my bags they were actually ilvl 46... but monsters dropping rare items when killed still dropped actual ilvl 52 items. Just a chromie-time thing I guess when over an xpac level, not an SL thing. But interesting, if not common knowledge already.
But yeah, the SL quest is auto-accept so there is no way around it except perhaps to remain in your final chromie choice forever.
[doublepost=1607268482,1607266369][/doublepost]So two additional interesting tidbits...
First, just noticed that Chromie is no longer an hourglass on the main Org map on my 48 (denoting she is "gone" to me).
And second, I locked that 48 to see what it was like to do teh storyline bit at 48 for quest rewards and such (assumed exactly the same) - but when i got to the part where the Oribos flight master sends you to bastion the first time, he disappeared. I completed the portal summoning quest and before I could talk to him both he and the other NPC summoner disappeared. Not only did he disappear from my quest location, he is gone from Oribos entirely... but just for me. I can see other players using him and flying away at his normal location but he simply is invisible to my level 48 right before i go to bastion.
Maybe just a bug, maybe more control-freak gating by Blizz. Who knows...
edit- I also went back and turned my XP back on and he was still missing, not a locked XP thing.
