I agree with some of what th3gatekeeper has said, but will insert that this iteration of the game seems to be demanding it be 2 distinct games. The Solo/casual player wants what he wants and the grizzled veterans of LIVE expect what they expect.
For both groups, the opposing viewpoint is unthinkable. The Vets ask themselves with wonder how anyone could WANT to play this game solo and in a Pug SC group or Warband for any period of time while the Casual players can't wrap their minds around dedicating hours of time within the same group "grinding" the same grind.
Catering to one and not the other is a mistake IMO. As much as I would like to say I solo a lot and enjoy it, I only solo in T1-T3. I have a metric sh**-ton of fun pugging T1 SCs and ORvR on just about any class; however with NA times T2 and T3 are kinda dead unless one of my regular T4 Premade or guildies rolls an alt with me. T4 PuG is tantamount to going to the proctologist for me. I won't do it.
Others have the opposing view of T4 and soloing and have expressed their views enough (and with enough pull) to literally change the game and how it's played. I believe that, in the long run, some (a very small number) of the solo players who are getting renown and medallions int he chaos that is the PuG SC will eventually rank up enough and have enough play time to leave the kiddie pool and swim with the sharks. If so, this will be good for the "Group" Play Fans.
From what I've seen recently, the DEVs are trying to buff classes, not nerf. This, IMO, is good. (Results may vary)
The new META for ^v^ SCs seems to be 2 pure heal WP, 1 DPS AM, 2 Engies, 1 (SW< Tank< BW "other"). It looks like the DEVs are trying to bounce MDpS out of a job with these changes, even though I don't think that was the intent. FoTM classes come and go - every dog has it's day. I'm confident that the DEVs will tone it down a bit or raise up another class or two. I hope.
As for NA playtimes, I play from about 8 pm PST to 2 am PST (yes I have an 8 am job too) and my 5 or 6 man group in VOIP have been getting regular and consistent pops. SOmetimes it's against the same Order premades and sometimes against relative unknowns. (read as "sometimes you eat the bear, and sometimes the bear eats you) It's Ok. It's action. Any action beats standing in a keep waiting for defense or laying dead at the feet of a bugged out craptastic Keep Lord while the 4 order players defending teabag you (actually jumping on my head).
I think my playtimes are early-early primetime for EU or something. Either way, I always have Old School premades to slam my head against in hopes of PvEing my way to an SC win.
I couldn't get my group on for the 6v6 night, but next time, given enough notice, Black Library (and friends) will be there.
