I'm increasingly convinced that play testing is an entirely foreign concept to Plarium and this seems to be clear with the hard faction war bosses.  Some while challenging can still be be dealt with.  Others are so ridiculously overtuned (tainter mirrorer in particular) I'm convinced nobody actually tested it. 

I have no issue with difficult content but content that clearly wasn't tested properly (or it wouldn't be released in the state it's in) and thus is almost impossible to get past.  It shouldn't take multiple player complaints to get content that's actually tuned correctedly (the recently announced chimera ram form changes for example).  It's not like Plarium is hurting for the money to actually test new content before it's released...but then again expecting any company these days to spend the money to ensure at least a somewhat balanced launch is maybe asking too much.
