The two aren't the same. Open beta people were part of a massive server test. They didn't login to every D3 beta patch to test for new bugs, regressions, give feedback, for the last 6 months. They played for 2 days.
Me for example, I "beat" the beta EVERY beta build, every char wipe, did it all over again, even though it was boring to redo same limited content over a dozen times. Why? To test the client.
I think a feat of strength is fair to those that put the time in for it.
Thats right, you sit behind your computer screen in that comfy chair with your Feat of Strength and Sigil claiming that its fair only because you had to go trough ALL that horrible TORTURE testing for months on end while open beta was just a couple days and we barely had to provide feedback.
I remind you that 100% of those open beta testers would gladly of taken an invite and test for months if they were allowed to do so.
Your logic is flawed.
Btw, how did you get yours? I am sure YOU were chosen random.. right? RIGHT? No you were not. You got your free. Also, I am sure all 100% of those Beta Invites sat there providing feedback as they tested for months. So I am sure all 100% invited deserved it.
None of it makes sense is all I am saying.
FYI, i was invited to beta by blizzard among a few other tech support regs , because our initiative in solving technical problems and time we put into helping people on tech support forums and our technical knowledge they considered invaluable to the beta. So i'm not sure where you think any "free" invite came from. It was given for time invested in tech support forums helping other posters. Hundreds of hours.
However, i also managed to get a beta key through the give aways, contests, twitter feeds, etc as well (means that were available to you, and everyone else). I used it to get a friend into beta. So this judgement is very much flawed.
As for torture? you played an early product beta before? Played MoP beta lately? How's running around with no mounts, crashing every time you see a turtle that's REQUIRED to progress (or even logging in for that matter, etc, going for you? That's very enjoyable gameplay right?
Beta's are betas, it's not a game demo, it has an actual purpose, and helping serve that purpose deserves some praise. If all you played was open beta weekend, you played a much more functional beta client then some of us did, I assure you. Putting time into this getting a praise is well deserved.
I did my fair of testing, and bug reporting. As a tech support reg in fact, even more so then most. As i also wrote guides, troubleshooting stickies, and worked directly with tech support and devs in getting bugs fixed and providing workarounds or others.
Now were there some that didn't put time into it like some of us did, apsolutely. But can blizz really micro tens of thousands of users to give feats of strength out to the deserving only? Not really. So they just do a broad achievement for everyone in closed beta to come as close a they can.
