In anticipation of Necromancer coming pretty soon to live. I was wondering which weapons that isn't class specific that you can use with gem of easing to powerlevel from level 1 up to 70 level quickly.
Edit: I don't know why whoever edited my title implied that I am asking for which weapons can be socketed with that gem. I am asking which unique affix weapons (Solanium allow you to use critical strike to create health globe on demand for instance) would work best for int/dext/str classes.
I am planning to solo-rift on the highest difficult I can alone. I may find someone to help me powerlevel. We will see.
Important Notice: I am not asking about contents that isn't out yet. But rather weapons that are released as of 2.5.0 patch version aka Armory/craft mat storage patch.

You just need a weapon with a socket in it.
As the Gem of Ease second bonus at rank 25, sets the level requirement of the weapon it's socketed into to level 1.
I used my rank 25 gem by crafting a level 70 legendary weapon with a socket, and put the gem in that to use on my new character.
If you have a great level 70 legendary which has inspired your new character, you can use a Ramaladni's Gift to create a socket in the weapon.
1The two other answers have not been updated to list weapons with utility effects for leveling. So I took upon myself to go ahead and list a few myself.
I am listing 2-hand weapons because they hit harder and at level 1 you don't need offhand stuff just yet. I am listing anything that has bonus experience guaranteed rolls and/or anything that comes with useful legendary affixes. I am excluding weapons that may roll without one of the three primary stat (int, dex, and str).
The Executioner - guaranteed bonus experience Burst of Wrath - chance to restore 20% primary resource Wrath of the Bone King - guaranteed cold skill damage The Furnace - xx% bonus vs elites is a must Sledge of Athskeleng - guaranteed movement speed + x% damage Heart Slaughter - guaranteed physical skill damage Ahavarion, Spear of Lycander - Chance for a random shrine benefit from killing demon The Magi - crowd control reduce times on you The Tormentor - chance to charm The Zweihander - guaranteed bonus experience Blackguard - guaranteed less crowd control time on you Scourge - chance to deal aoe damage as fire Stalgard's Decimator - chance to deal additional damage The Sultan of Blinding Sand - chance to blind enemy Maximus - chance to summon demon pet and guaranteed fire skill damage Blood Brother - chance to block damage and deal more damage Corrupted Ashbringer - chance to summon skeletons for pet and aoe damage
