Guild Wars 2

since stats will be removed from traits, then how will we increase our secondary attributes?

Secondary attributes
In contrast to primary attributes, the five secondary attributes have a base value of 0 and do not automatically increase as a character gains levels. They can only be increased by spending points in the relevant trait line or with equipment bonuses.

Boon Duration
Improves the duration of all boons applied by the character.

Condition Damage
Improves the damage done by the conditions bleeding, burning, confusion, poison, and torment.

Condition Duration
Improves the duration of all conditions inflicted by the character.

Ferocity
Improves the damage multiplier on critical strikes.

Healing Power
Improves all outgoing heals that your character does, including self heals.

especially boon duration and condition duration.

I would guess that duration is going to be one of those things adjusted first on baseline and then the rune/sigils well probably be reexamined.

This is an emerging question that must be answered, especially for condi builds.

best solution by far would be to let us chose which stats we want the (up to) +300 stat boni for

just like now but separated from traits

so basically a second window like the trait-window but only for stats

why doesnt anet do it like this
it actually improves the current situation!
and everyone would be SUUUPER happy

people could keep their gear and dont have to craft new ascended gear parts for all of their chars to get the right stat mix again

also people wouldnt be forced to have stats they dont need for their build
because for example:
getting 74 power, 74 toughness, 74 precision, 74 vitality +gear stat increase as compensation for losing 300 condi dmg and 30% condi duration is a hit in the face to condi build players from anet

I think boon duration and condition duration are just gone except for runes, sigils, and select traits. Global increases to boon and condition duration caused too many balance problems.
