Frankly speaking, it is quite disappointing that ever since the import of new scripts (let's be honest here, this core came from somewhere, most of the things that were in ICC had already been scripted and it is impossible that Warmane staff did it all by themselves) the overall quality of raids has gone down from rather well done and rounded up to impossible to finish raids. Now, of course one could say that these errors in scripts happen all the time, that's nothing new but the issue here is that the newly implemented 'features' that come to live are not even tested in any realm, whether it's PTR or some closed realm. Also, I wouldn't even want to get started with ToGC or Ruby Sanctum raids which are in a terrible state at this moment.
All in all, I believe that today we've done really well considering the broken Val'kyrs, 5 Raging Spirits and a few other bugs while running lower DPS than usual but, and I believe I'm speaking for every one of us not only in guild but on this particular server in general, it'd be absolutely fantastic if there was some sort of testing period and actual announcement of what was patched up (not just "Hotfixes incoming, realm restart in 15 minutes").
