They sure could improve the new player experience. At least put a little option to deactivate the "new player" experience and add a little warning when taking the introduction quests of each expansion. Or even better : add a little note on each quest dialogue specifying the corresponding expansion, or even patch.
Yeah, but as long as it's not mandatory. Exile's Reach is good, but it's stupid that players that want to start wow after playing the three warcraft rts have to skip 7 expansions.
