If you have these expectations towards Early Access you had the chance to inform yourself upfront whether or not your expectations will be met, before making your purchase.
User called @Angel asked if there will be wipes and if one could expect characters to be carried over to 1.0 on the 8th of March, as you can see for yourself here: What is going to happened with early access characters
@thomasmahler answered only a day later saying this:
Impossible to say at this point.
Fully depends on how much we’re changing throughout Early Access.

That being said I do not share the expectations you have for Early Access titles and don’t think they are justified. The guarantees you demand are not something that should be expected from a title that launched with the idea to be refined with communities feedback. It launched this way, because they wanted to change, fix, rebalance and improve things based on community feedback.
You did not buy a finished product and you are definitely not doing QA work.
In fact in 74 hours you claim to have played, this is the only topic you created and replied to.
