I think a lot of us already knew deep down inside that this so-called expansion was going to be a failure even before it went live. I sure as heck knew... I mean, look at the quality of content they've been releasing these past few years. They can't even properly balance a FLASHPOINT anymore. Look at secrets of the enclave for example. It is possible to do that entire flashpoint on master mode with a group of 4 DPS! You don't even need to have a healer in your group to complete it, and it is significantly easier than VM Hammer Station. Ask yourself why they would make a MASTER MODE flashpoint easier than VM HS? Let me tell you it's because the devs have no clue what they're doing. Remember how underwhelming SOV was? Again, trash mobs in hammer station hit harder. The devs can't even balance a fp properly. And remember when they released all these new sets of gear and augments that no one needed or asked for such as 258 and 306 gear? You know what's funny about that? They were too lazy/busy reworking the gearing system as per the usual that they didn't even get around to the most important thing, rebalancing the content! So we had massively overpowered tunes running around in full 306 gear doing 16k+ dps when 6.0 launched. Yes, It became more difficult to survive on some missions, but everyone started doing tons of DPS so most content became a joke.
7.0 is the complete opposite of 6.0. All that freedom of gearing and "play the way you want" crap? GONE! Instead of letting everyone remain extremely OP, they took away abilities that we've had for years, retuned all of the content, and are forcing us to wear crappy green / blue gear. Now all of us will feel 10x weaker when we play the game, even though we're used to feeling so overpowered. Smart devs, huh? And yes, you also have to look at the ugly UI and put up with a ton of bugs. The developers obviously don't play this game or debug their own code. They just write it and hope for the best.
