Guild Wars 2

Hi I know that most people wouldnt want to get the Bifrost because of the rainbow thing but I wonder, will it change during battle? does anyone actually have it as a necromancer? I like the aura u get from it because it looks like ur standing on the gateway to heaven like “Come with me child I shall take u to the other side” but thats about it….

I was thinking of going with frostfang and incinerator but the question is will they blend?
Frostfang makes the arm go ice and gives ice trails, the Incinerator will make the arm go Fire and leave fire trails, since they will be held in different arms I dont think that the arm effect would be a problem but what about the trail? will they blend? would u walk with fire and ice?

Im currently playing with scepter cause I cant find any viable play style for Solo/PvE/PVP but I will change to axe if its worth it.

My last question is, will there be new legendaries and how long until their release? do we have to discover them or will they be posted on their web?

Thanks for your answers and time to read this post.
