Someone has to say it:
Jump!
And then summon my chocobo and jump over as many fences and boxes as I can find

And after about 10 minutes of doing this I'll get sick of it and start exploring for a a little bit, trying to "test" the adjustments to the battle system as a lvl 50 on lvl 1 mobs while getting angry that they die before I see if anything really changed...

And then I'll log off with a sigh and create a new character to see how 2.0 really is as a new player
