SWTOR is a great game, don't get me wrong, it's just way different. As you said, it doesn't feel like something competitive and fun at the same time. That said, it REALLY nails immersing me in the story as an insanely badass sith Warrior who is basically wrath incarnate. I'll play it when I'm bored of WoW but I don't see it replacing WoW.
Yes, Blizzard is really milking us. One of the biggest reasons I will stop playing WoW is because releasing two raids with 7/8 bosses in a row was an absolute slap in the face. Content is good, and having both LFR and Normals are great, but I don't think blizzard realizes that we want content that is challenging for our level of gameplay without being too harsh. I think that other than Hagara and Blackhorn, Dragon Soul fights are fun and challenging on normal with a gradual difficulty ramp as you progress through bosses with the the culmination being an excellent Deathwing fight that feels pretty epic and is fun and well-tuned
However, 8 bosses is just NOT ENOUGH. The heroics are fine if you're more of a hardcore guild, but we're not. Yes, we'll get a few down but it will be very tough. Tough is good if you're in a raid group that shares your mentality and skill level (AKA a hardcore guild) but our guild has a large disparity in quality and commitment from top to bottom. That's not a knock on our guild, we're a casual guild. Blizzard needs to realize that most guilds are like this. We need more content that is challenging without being unforgiving. Did we ever feel like Spine or Madness were unforgiving? I didn't. I felt like they were well-tuned and we were slowly getting better and executing better until, BAM, we got the kill. Now compare that to like Heroic spine or something, where the best guilds in the world spent hundreds of attempts on it and even when they killed it (By class stacking like nobody's business), they said that they didn't want to repeat the kill. That's not a fun fight for 99.999% of the guilds out there. Hell, it's probably not a fun fight for 100% of the guilds out there if the best in the world are complaining about it. How does blizzard expect us to be happy with content like that?
And don't even get me started on the loot! It's a goddamn nightmare to assign loot when there's only 8 bosses a week that drop loot, and we only get 2 tier tokens per boss for a goddamn 25-man raid. Seriously, wtf is up with the tier. You guys have no idea how much I hate doing loot because of how many tough choices we have to make on every boss. While most of the raid have accepted accidental slights or terrible RNG with grace, we see how frustrated some of our core guys can get when they have 1-2 pieces of loot after we've killed a total of 26 bosses in DS.
They needed to release at least three tiers of additional raiding after T11, each with 10-14 bosses. Instead, we got Firelands and Dragon Soul.
TL;DR: Blizzard needs 12-13 bosses per raid. They don't give a shit and are content with releasing two 7-8 boss tiers as a TOTAL amount of raiding patches for an ENTIRE expansion. Un-fucking-acceptable.
