Guild Wars 2

Give beta characters a complete set (weapons, armor, trinkets) of legendary stat-selectable gear with ugly standard skins.

While a beta gear vendor would be an improvement over boxes filling your inventory with gear you can’t use, even better would be just one set of gear for which you can change the stats anywhere.

We also need unlimited access to runes, sigils, and maybe infusions; maybe an unlimited use item that lets you select an upgrade to add to your inventory? This is especially important for testing rune bonus interaction with new skills.

Would it be a bit easier for players? Probally yes.
Does it matter? Not at all.
This is a test, and i’m sure there’s way more important things to do then this.

It’s not like anything I’m suggesting requires new tech. Selectable stat gear exists. Items that bring up a menu for choosing other items exist, such as ascended chests.

I dare say these ideas would be trivial to implement, and allow players to test to their fullest capacity.

It’s not trivial, else it would be so, seriously do you really think if this was a 5 minutes job that a-net would bother with putting multiple chests in, wich you can select your stats for but not while it’s on you?

There clearly is something in place that does not allow what you are suggesting. Stop acting like the devs are bloody kittened.
