Horde tactic with BiS tank + 3 healers + frost mage FC team while Ally always have only melee damage in pugs is indeed tiring and just boring most of the time. Seeing Smooglab and similar warriors + 3 healers taking flags from druids or good mages like Dms every 2nd game and just sitting on a cap spot because they know Ally team is full warrior/hunter and that they do no damage to him, while mage slowly pick them out 1 by 1 is just lol.
Also, I agree that there are some classes which REALLY lack good players. I don't know about Horde situation, but at least on Alliance there is only 1 active warlock who can play in good premade, 1 or 2 rogues and no druids. So if those 2-3 players aren't online, you are forced to play without 3 classes from start.
However, the alternative is playing on LoS-less Elysium which I personally found less enjoyable overall even though there's much more good players and competition due to huge population.
And besides, pretty sure that Sachi was referring to 2 games we had around 1-2 AM last night right before his post with 5-6 Ally semi against what seemed to be 8+ Horde group. Having couple of casters for a change made their warriors die easily so they actually used their druid most of the time which made the games fun. Had few similar fun semi v semi over the last coupe of days as well, much more then anything in the last month or two, pretty much since the original Fight Nights died out. Sure, there's too much tanking melees in pugs, but had fun games too.
As for the merge, I don't think anyone expects that it's going to boost the quality of PvP directly, but just the activity. Now, with bigger activity both in BGs and WPVP there are good chances that some players might start playing again, since slow activity was the main reason why people started quitting the server, except for Nostalrius players who returned to their old characters. I know for a fact that few solid players could be back after the merge, if every 10th person knew 2-3 more, maybe we could have more competitive environment soon. Sure, the merge might as well be just a fail in this department, but for now all we can do is hope that it's gonna bring at least some improvement. If not so be it, for me personally it's either playing on Kronos or quit the WoW, so as long as I'm interested in the game (Kronos), I'll try to make the best out of it.
In the meantime, let's get some 10v10 games going shall we, Horde had more then enough "premade players" active again lately, which was the stumbling block for such battlegrounds in recent period.
