Ya this list is pretty great.
So post-patch you can queue for:
[x] Wanderer's Palace
[x] Amador Keep
[x] Castrum Meridium
[x] Ifrit HM
These will fill up your 5 slots that you can queue for at once. After you get the Ifrit Weapon you can queue Garuda.
Start moving your relic along while you wait for duty finder to pop. And, of course, watch your Free Company chat for runs of any of the above. Always more fun with friends! Post-patch you will be getting Philosophy and Mythology Stone for pretty much everything. Start filling in your lowest gear slots with Darklight gear.
Here is the important part: IGNORE THE FOOLS who say you are under-geared for blah blah blah. Yes you are, that's why are are running blah blah blah.
I can say pretty confidently that you can win nearly all of the runs above with mid-range gear. (You cannot have 4/4 party of fresh 50's and win at Amador Keep, BUT you can win with 2/4 people fairly well geared.) Learning the fight is what you need to do, and to do that, you need to go do the fight. (Watch a video if you are so inclined). But really, just go do it have fun and remember:
IGNORE THE FOOLS.
The only thing you should not
do is try to progress through Titan Hard Mode before getting decked out in Darklight Armor and have at least one Primal Weapon or Relic Weapon. That is your goal, and getting there is fun! as long as you IGNORE THE FOOLS.
There are a TON of great, reasonable, helpful players out there who are A) also trying to get better gear, B) remember what is was like last week when they were still working on better gear. These guys are super fun to play with. Woohoo! You will be helping newer-players-than-you learn the fights in no time.
Honestly really impressed by the way the recent patch evened out the incentives for the current Lvl 50 Dungeons. The are all getting play time now.
Bahamut's Coil, here we come!
