I doubt it took me that long to unlock everything. In fact, I think I needed half the time of that at most. You don't have to spend more time there than needed, though of course it's appreciated when you do.
I calculated that I get for over 110 Euros worth of goodies and that was without the dilithium added on top of it. (I have 11 chars and the more chars you have, the more value you get, if I only had 1 char I'd get for less than 20 Euros woth of goodies.)
I don't regret my time spent testing, despite the frustrations it is nice to see the incoming changes. Also, if I received a 100% reward for my time spend I'd not be helping out Cryptic, but working for Cryptic instead. I'd basically be on their pay roll then and I'm not sure how I could explain that to the tax department. Especially not when they ask me to pay taxes on the goodies I earned by testing for Cryptic.
What always makes me laugh and cringe at the same time is people that go into a test server looking to make out like they had a contract for $. Please people - its a test server and we volinteer to help find bugs and try to break things.
Cryptic like any over developer I have ever beta tested for - "always" gives the folks that stuck it out and helped something in the endl. Be it ingame gear or a free copy of the game b4 launch. Something I have pondered often is why anyone would help out on a test server of an established game if they did not have a passion for the game and desired to have a chance of verbal input to help influence the outcome of something that they cared about.
I could go on and on but bottom line - if you do not have a desire to volinteer and do not enjoy yourself (at least most the time) don't bother jumping on any test server. And please don't come onto the forums for said test servers and whine about it.
