Should I be worried?

No

I was wondering about it myself, what kind of raids are available? And do the weapons ever look unique?

Theres a total of 2 different operations, including 6 bosses total for now. Right now its pretty bugged, no loot, evade, get zoned out, ect ect, dont bother rushing for end game yet lol.
That is for PVE, you can always do Heroic Flashpoints, they give good gear but some of them are a bit bugged aswell ( mainly last boss chests ).

PVP is where its at right now Farm those Valor ranks and hunt those datacrons lol.

I don't even bother looking for datacrons. Each one only gives +2 to any stat. Not worth my time right now.

When I have full Tier 1 PvE gear and am capable of doing 16-mans, and have my EPic mount, then I'll start hunting them.

I really hope endgame content is amazing, I'm only level 12 and this game is so amazing already.. would hate for all this hype that I'm building up from leveling doesn't come to an abrupt halt at 50

End game is fine.

End game content is consistent with other new MMORPG end game content.

Even World of Warcraft barely had any endgame content when it was new. A lot of endgame content takes a lot of time to build up to.

"lfm darth vader have all datacrons found"

Can't wait.

just makes me laugh a little knowing that people have been rushing to hit 50 for basically no reason. I am sad though I basically had to switch servers for now, the one I am on is so damn full I can barely ever get logged in before I need to get off the computer.
