Legendary thoughts...
The scepter have no advantages since its crap no matter how pretty a skin you put in it.
IMO its really quite simple – dont think on it yet. You dont have to decide. Do the generic gifts common to all legendaries (fortune/mastery), see what kind of material stocks you have. Keep in mind thakittens 1200g+ worth of materials in total.
Cost of the precursor is a factor yes… But it should not decide what you do in the end.
AFAIK, Meteorlogicus has no footprints and no particle effects. I doubt anyone but you would even know you had it.
I agree with gathering the common components for now. Anet stated that they plan on adding more legendaries before the year is over. It may be worth it to wait and see if something better comes out.
There’s no harm in waiting. The average player would probably take 3-6 months, so you don’t have to decide now.
Of the two choices though, The Bifrost by a huge margin. Heck, I’d probably consider an off-hand before Meteorlogicus.
I know of a Mesmer who has the Meteorlogicus and it actually looks really nice on an Asura. I’m not sure if I want to go for Meteorlogicus or Immobulus now.
I personally have a Quip and, with the recent change, love it [even more]. Clones wield offhands so they all glow Purple with me.
