It's worth mentioning that leveling was also made easier because
so few people were around to help out. Through Vanilla, if you had a
tough group quest, you probably had people in your zone on the same quest you
could group with. WoW accounts for sale By BC, there was no point - nobody was there any more.
You skipped them and maybe came back later to solo them at a higher
level, or if you were lucky, you had a much higher-level friend who'd take pity
on you and come carry you through it.
This happens in almost every MMO at some point. Some have
built-in ways around it (GW2's scaling). Others do nothing: I had several
players tell me it wasn't worth starting Final Fantasy XI a few years ago
because I'd get stuck on un-soloable content and would never find anyone to
group with.
WoW dealt with it by getting rid of the hard leveling content,
adding a dungeon finder, and tuning the dungeons with a fairly low set of
expectations (because if 3/4 of your dungeons end in failure, players just
won't do dungeons any more).
CRZ could have theoretically fixed it too, Where to buy wow
accounts but I guess they didn't anticipate
implementing it when they "fixed" the world for Cata.
Technically we start around level 15 when we can start entering
instances. All those instances while leveling up? That's where we
originally learned to tank, heal and dps within a group. Now it's nearly
impossible, thanks to speed runs, BoA gear, and impatient players who just want
to level up faster. Proving grounds helps solve this learning problem you
speak of. It does not help! When players exit the proving grounds, they
will meet the same impatient players, with BoA gear and speed runs. This thing
won't solve anything!
Exactly. Change the stupid "go go go" attitude of the
players and you can learn your roll.
As it stands now, I'm leveling a Druid healer and Warrior tank,
both in the 40's and it is impossible to actually "run a dungeon
correctly."
Asshole players pull everything, run ahead, engage bosses, etc.,
with no consideration to any other player. If you want to take a dungeon
seriously, you'll get vote kicked.
The problem isn't game mechanics, it is players. Get rid of the
players and the game would be fine.
