Here's my petition for core professions to gain a new weapon. Anet has a policy of adding new weapons only through the Elites, which breaks an immersion of have a more versatile profession. Some professions are very focused on some utility and leaving the other part very weak. There are many ways to add these weapons without being exclusive to an elite, I going to write two ways.
Quests and Achievements
We can use quests similar to "Knight of Thorns". It is not easy but it is a great journey. You have to collect items to get new learning
Quests and Mastery
Something similar to Skimmer's diving ability, a series of quests that in the end unlocks a Mastery to achieve.
I can give the example of why professions needs a new weapon.
The Necromancer, the only main weapon of direct damage is the axe, if you want to play with power build, you need to have the Reaper to achieve significant damage, because all other weapons are focused on conditions.
And also the Condi Engineer, core has the pistols but it doesn't even come close to Holosmith's sword, which is actually a hybrid.
I don't see even a cons against adding new weapons to the Core.
I will leave below what I see missing in some professions.
Something melee, like axes. Let it be as quick as the sword and have dexterity too. It would be totally focused on Conditions, the arms traitline is great but is only used for the Flamethrower critics.
A gameplay like that of the Warrior with two axes would be very good.
Revenant deserves a decent weapon to represent the demon from a distance. The only weapon with Condition damage at a distance is the shortbow, which still doesn't even live up to the demon, the skills are bleed and fire, the devil has torment and chill.
The Revenant trident is a very good creation because it depends on the legendary summoned, but unfortunately it is only underwater.
Mixing these two ideas, a scepter emerges, attacks from a distance and may well fit the idea of the trident.
The only power weapon is the axe, as in the example above if you want a Power Build you will have to play with Reaper, so you will have the Greatsword which is a great weapon and then it gets stuck in Axe and Greatsword. To have greater diversity with Power Weapons, the hammer would be a great option. Functioning like the Deadeye Rifle, but instead of kneeling, the weapon's distance is changed, thus changing the hammer to melee or ranged.
There is a lack of weapons diversity as the Engineer, I know that they have less weapons because they have a varied choice of skills, but the Elementalist in this case was very affected.
The only weapon with a long range in the Elementalist is the staff, which in this case is the worst weapon, is very weak and very slow.
So he deserves a long range weapon, a Longbow and a Greatsword like Mesmer would work perfectly.
Both weapons are agile and strong in the other classes, it could be the same for the Elementalist.
What the Elementalist really needs is a complete rework, that is a fact.
