Iv been trying to think of ways to solve this cause it really is a major issue, apart from putting the decent alliance players at a major disadvantage, it renders games unfun for those of us in the horde who can actually see past mid and play the game.
The trouble with revival threads and "start-afresh" things is that everyone gets hyped for perhaps a week or 2 and then, as with everything, it dies down with maybe one or two players left who will eventually quit out of boredom from solo queuing. Also, asking people to uproot and move server/faction is more difficult than it was before because of the money aspects between enchants, the rep grind for new BoAs, the money for those boas and then the grind for normal BoAs. People arent willing to invest so much time just to play 19.
I know that in Atoma, our number of active members has been increasing from a few factors. Quite a few of our new active players have rerolled as a result of watching us duel outse org. They would ask questions, and be answered enthusiastically; they seen a group of players who could work as a team, communicate effectively and most importantly have a good laugh iwhile they were doing it. An experience which they (and most definitely I) have never really had the pleasure of at 85.
Also, earning(if im allowed to use that word) some kind of reputation in battlegrounds has attracted people to reroll/migrate to come play with us, resulting in an even larger, happier, more fun guild.
Where all that stuff fits in to your post about attempting to bring up the standard of players on alliance is somewhat cloudy, but I reckon that a decent foundation is all that is required on a server. Could be 4-8 active, enthusastic & friendly players "advertising" their twinks to likeminded 85s. (but not in an in-your-face recruitment message in trade) Could be some other way, I dunno.
The sad truth is, I don't really see many potential ways to bring up the level of player we are seeing more and more of these days. It seems to be that twink guilds have to rely on snowballing (even if it takes a while to start) or dying, which is a pity.
In my opinion, we need the community
here to get playing in good 85 pvp guilds and start twink "branches" within them. This could at least bring up the skill level a little bit, because frankly its shocking the amount of backpedllers and keyboard turners that still exist, yet have the brain capacity to lock their xp...
Anyway I'm just rambling now. Will be returning to 19 after a couple of weeks break and will be playing on alliance for a bit, but mainly horde. We'll see what happens if the ally defecit is as bad as it sounds
