It would be nice if there would be a Healing power main/toughness/vitality armors, weapons and jewels for more tank/support role so rest of the team could go full dmg without being afraid of dying or getting unwanted agro.
there could also be runes with main healing power/remove conditions/boon duration stats to go with that kind of armor.
And lastly sigils for weapons, it would be nice if there would be “on weapon swap cure x conditions” or heal nearby allies, or give aegis, or stability, so people can actually support better while swapping weapons when needed.
