I've not played this game since just before burning crusade came out, I think when the max level was 60? I'm just wondering is it worth coming back now? Like starting fresh? If so I have a few questions;
Plenty of people think it's worth starting (and restarting). I'm certainly having fun.
Which world/realm is best suited for me? I'm from Europe and I like PVE.
Are there any guilds recruiting within the world suggested?
There's a realm choice, choose a european PVE server that isnt too full. There's a lot of cross-realm activity built in these days (though still no trading). There are always guilds recruiting - guilds can level now and gain rewards which assist all members, while the guild benefits from more members. There's a built in guild finder where guilds advertise.
I like rogue/thief type classes how has Rogue changed since vanilla wow?
has changed. The talent system has had a complete overhaul, further customisation comes from 'glyphs'. But the role is much the same. My main is a rogue and he's still enjoyable to play.
Also, pet battles. Enough of a reason to rejoin in and of itself. :P
I'm more of a casual gamer nowadays, is it possible to log in do a few quests and then log out? Or does it take time to do things nowadays? I'm coming from ffxi/ffxiv where everything takes time, and I don't want to waste countless hours waiting lol.
I can't vouch for dungeon queue lengths at lower levels, but levelling is considerably faster than it once was and I've never really sat around for much (I don't raid). If you do find yourself sat around waiting, there's always pet battles to keep you busy :)
