Guild Wars 2

Hi, guys. After much turning around I think I understand how the new Elite of our beloved Elementalist works. First of all clarify that this is MY THEORY as systems analyst and player.

Well, the rumors and filtered images suggest that the Elementalist will have:
Sword of a hand
Only 2 Elements at a time
The third skill will be different
Mantras

There is much controversy for this since the grace of the Ele, is to have 4 elements, which gives about 20 abilities. And according to the rumors having only 2 elements will reduce the amount of skills to only 10 (plus the 5 support)
But how about if they would continue using the 4?

I think what you will have is a CHANGE OF WEAPON, maintaining the same 20 abilities. Remember that the reason why the Elementalist DO NOT change weapons is to have so many tunings. If at 20 we add a change of weapon would be 40
But it seems to me that the idea will be that the elements will be divided into the weapon changes. That is to say that they will be 2 Elements for one set of weapon and 2 for the other one and the third ability of a set would be interchanged with the one of that in off

Let’s take an example:
Staff and dagger / focus
Fire and water would be available ONLY with baculo, although the 3 of baculo would be really 3 dagger
Air and land would be with Dagger / Focus with Baculo 3 available.
With this we would have an interesting combination that mixes and collects everything that is known until now and fits it to what would be a WEAVER (This will be called the new spec supposedly
They would be the same 20 abilities that were distributed between the two weapon combinations. A great change no doubt. And a way in which developers work (as I said they are systems analyst and I think this will be so)
What do you think?
