Its not about where your going, but what you do along the way.
Yer, loosing your life along the way

That is indeed what you do.
The problem with WoW is that the main objective...to be the best, have the best gear with the best stats is so time consuming it totally takes your life away. That is the point, playing casually is not the point of WoW it is a by-product.
And you can't really be a casual player since you never get to see end game content as guilds expect commitment. Basically to Raid and see end game content you need to be playing 5 hours per day at least, i.e. every evening if your in a guild which makes progress and gets the tier/epic gear.
Not everyone enjoys the Raiding life either. Same dungeon, same mobs rinse repeat every night is tiresome even though at the end you can stand in a virtual city in the game letting lower levels inspect you whilst feeling like a demi-god as you have uber epic gear such as the Sword of no life, Shield of a Looser, Helm of a Nonce etc in your inventory.
Assume it takes a fast leveller 6-7 days to 60 then another 6-7 from 60-70. Ok so it can be done quicker but on average this will be much slower for the majority of people. So 1-70 is 14 days = 336 hours just to get to the level you can go for the epic/tier gear. Double that to get yourself reasonably kitted out and your looking at 30 days game time (as a good player in a decent guild) or 720 hours.
I know players that have taken well over 30 days (720 hours) + just to get to level 70 alone, never mind going for the gear at the end.
As a casual player there are still options at 70 if you don’t go into a raiding guild.
1)Level more characters – in fact buying the game and using a game card + generic name/ID and levelling priests, druids, warriors and mages to 70 can be quite lucrative since these accounts can sell for decent money although its against Blizzards t&c its easy to do ££££.
2)Farm items to sell for gold then sell your gold to gold sellers or other people for real money £££.
3)Level characters for fun and not to sell. To me levelling and the fun + social along the way, is the best part of the game.
4)PvP in battle grounds and in the game world if on a PvP server. Ok so it’s a bit of a point and click effort but good gear can be had this way and its more fun than Raiding since people aren’t so predictable as a generic mob boss which does the same move at X% of his life or every XX seconds which you avoid by blah blah blah...
5)Level a Rogue to 19 and then get all the best gear for it and enchants then PvP annihilating everyone else since you totally out class them which is also fun.
