But bugs that render HM FPs unbeatable, FPS issues etc. are unjustifiable.
There are no unbeatable flashpoints. They've all be beaten - many, many times.
@op: You just made a post critiquing content that is horrendously bugged; This serves no purpose. HK and Revan are clearly not intended to work the way they currently do. Once they fix the multitude of bugs, you will be able to steamroll the entire flashpoint in fresh 50 blues, because it's fundamentally easy.
