Have you tried tanking as a lowbie tank against synced DPS in the early levels (1-29)?

Now imagine someone Deathflare/Holy/Flare the entire group and you lose hate after 2 Flashes/Overpowers/Unleashes. Yeah... Not fun. Things will die faster and be better for the higher leveled player yes, but it would be a bad experience for the newbie tank who:
1) Won't get to practice tanking rotations
2) Will get crazy expectations when running with similar levelled players.
