Crit, several of the players were indeed simul-queing from other servers, and out of respect I shall not name any names. I DID notice however, that none of the HI folks talked out against it, or encouraged otherwise. If nothing else, they are guilty of complicity.
The point is, I have several Horde toons on Aerie Peak, and used to be a part of full 15 man AB and 10 man WSG games. The problem is, I realized that it's completely unfair, fun, or usually any kind of a challenge. I especially felt bad when we faced Alli teams full of TRUE trials who barely had a clue, they just got destroyed. My only consolation in those games was that we NEVER farmed, and we ALWAYS capped quickly. Now, I tend to solo que, or que with just a few others (mostly to counter the 6-7 Alli hunters we usually encounter).
You say you want challenging games, well as a full 24 premade you will NEVER have them, end of story.
On a positive note, as I was leaving the vent server, there was discussion of wargames. I think this is the ONLY way you can ever expect to have fair and balanced games as a 24. To think other wise is deluding yourself.
I speak from experience, I had a 24 for about the period of 2 weeks. In the end, playing him was unfair and really not even fun. I ended up deleting him. For perspective he was a 24 feral and with all cooldowns, there really wasn't many trials in the bracket who wouldn't immediately go down.
I have been twinking since Vanilla, and it is true that the VERY essence of twinking is maximizing your toon in every conceivable way. But the 20-24 bracket IS different from every other bracket with the level and stat disparity between 20 and 24, XP OFF ofc.
From another perspective, on a P2P twink most of the work is done quite easily with a main. F2P have to do it ALL themselves. The harder it is to accomplish a thing, the more rewarding imho.
