After about 3 hours of being level 50, it hit me just how much there is to do at this level. It's a bit overwhelming, but I'm sure that with time I will have a better idea what I'm interested in, what I need to do to advance my character and what I consider a good use of my play time.
One of the first things I tried was a hardmode Black Talon run. Someone was looking for a healer, I whispered him that I just hit 50, so I'm not sure if I'm ready, but I would give it my best shot if he'll take me. Turns out the tank was also a leveling geared fresh 50. 30 minutes later I learned my first lesson, a completely ungeared group of 50s can't make it in HM FlashPoints. I know some of the guides claim it's possible, but considering the first boss was hitting our tank for 50% of his health every 1.5-2 seconds, I wouldn't recommend trying it until you have some better gear. I guess that's what the normal level 50 FP are for, there are 4 of these.
