Wand selection on vendors is insanely OP and imbalanced

Why are there so many more wands than any other type of weapon on vendors? Every level a wand user gets at least 3-6 new wands to purchase. The chances of you going 2-3 levels without getting at least one 3 link is pretty low for wands.

If you're using a Scepter you get 1-3 scepters every other level. While basic wands are available every single level, basic Scepters are not. I don't know how many times I go through act one and maybe even half way through act 2 without seeing two 3 links scepters. Yet, it's very rare to go even to The Ship Graveyard without having multiple drops and vendor 3 link wands.

Wand users get at worse about 40 wands chances between lvl 2-14 while a Scepter user at best gets about 21 different Scepters to choose from, and that's about the same for melee users as well. By level 62 wand users are looking at about 183 wands to choose from at worse. Other weapon users are looking at 93 at best. At best a wand user has around 372 wands by lvl 62 for purchase, and every single one of those wands if lucky gets a +1 to all (insert) can easily carry the wand user into yellow maps.

You don't see Gwennen offering 4 wands every single re-roll, you don't see Gwennen offering 3-6 heavy belts every re-roll, yet you will absolutely see that kind of re-roll on the wand vendor.

What +1 lvl 3 sword or ax can carry a melee into yellow or even white maps? It's seriously OP and absurdly imbalanced at giving wand users a massive leg up.

How about having Scepters be available every other level on the vendor instead of wands? That at least would be a lot more fair.
