That's what I'm talking about. There's no way Onyxia is a casual player's paradise. Regardless of whether there is Blackrock or not at all. Casual play appears around the legion addon. All previous expansions are wild grind for 24 hours a day. You either devote at least 5 hours to the game every day and make progress, or come in once every couple of days just to kill time.
The fact that you haven't got BIS pvp gear on Onyxia for at least 2 months is your problem, not the problem of the new server. Those who wanted to, got all the necessary to play in TBC even before the opening of the portal. And don't talk about the cost of sockets. They cost 20gold a piece. 20gold is to sell 2 green items or do 1 quest. It's faster than winning a BG.
I agree that it will take longer on Onyxia to create a new character, or for a new player to start the game. You will need to spend about 24 playtime hours first to get 70lvl, then about 30 hours to get a pvp gear. But that's the whole cosy atmosphere of real TBC content. You can have wpvp fights, you can gank, you can dilute the routine with a PvE aspect. You can buy the item you need by going on a goldbid raid. We don't have all that. But we don't need it. We can only spend our hours on BG and arenas. But in the same way, if I want to create a new character on Blackrock now, I will suffer the same way about 30 hours of game time, until I will get pvp gear and can fell myself good in BG and arenas. I'll just skip lvl-upping part of the game. Personally, I'd rather spend a few days on BG to get the item I want than spend just one day in pve. Because I like pvp and I don't like pve.
Stop crying about someone getting useless stuff without spending time on it like you. For BG and arena play, the stuff that Blackrock players get at startup is absolutely useless. Absolutely all of them need to be changed. But if you, like me, don't need full freedom of action, don't need the PvE aspect, don't need the full atmosphere of the game as it's designed, and only PvP content is enough for you, what's stopping you from stopping crying and switching to Blackrock like I did?
