Two things FF14 can adopt from Guild Wars 2.

[Drakkaelus]

I'd love for #1 to happen. Or for SE to at least give you more attacks at lower levels. Or something to make doing lower level dungeons fun. Just spamming 2 attacks for an entire dungeon isn't fun. It wasn't fun when the game was new, it's not fun now. How anyone could possibly think that Fast Blade -> Savage Blade 100,000 times in a row constitutes engaging gameplay is beyond me.

1. This would cause more problems. People would forget what levels skills become available, and berate new players or levelling jobs for not using skills they dont have, or abandon low level duties because they got paired with newbies.

...why would you think that would happen? Do people forget what level gear is distributed at and yell at lvl 20 players for not being decked out in lvl 70 gear?
