Guild Wars 2

Hey so i like the idea for the 2 sigil slots on 2 hand weapons (mainly for my rifle engi) and i liked the idea of how you would be changing the runes which is also a buff for me since i wont have to go 2/2/2 runes anymore.

It seems the runes will be moving towards a more universal style like Runes of the noble in which they give condition damage, might duration and 3 might on heal, which is a great rune for engineers because it removes the need to go 2/2/2 runes and gives us extra of everything we need, however also a newer rune, Runes of perplexity (i hate em) the are the only rune that is used offensively to utilize its bonuses(3 confusion on attack, 5 confusion on interrupt).

Will we be seeing more runes that can be used offensively to utilize there particular bonuses or since we will be able to use 2 sigils will runes be only able to stack any sort of damage in there current form (example:5% chance to inflict bleed when struck)?

if you do change runes to take more offensive ways to stack damage wont it potentially make the condition meta even stronger, or alternatively if the rune gives a power based damage bonus, (like a Rune of Air but functioning on attack and not a buff when taking damage) will allowing them to stack with a air and fire sigil become well overpowered considering there would be 3 going off all the time?
