How have you leveled 50+?

[Natsuki]

i just made 53 last night, and i was basicly just doing the MSQ and some fates if i happend te be close, some sideqeusts as it seems you need to do some for you flying chocobo, and ofcourse here and there some roaming mobs i encounterd while exploring the map ! (oh crap ! that mob has a way higher level then me ! RUUUUUUUN )

MSQ, (gathering and crafting) leves, gathering, crafting. Also doing collectible turn inns.~

Low Level Dungeons still give out a fair bit of experience.

where's the shop that sell gears for new tomestones?

You'll WANT to level through the quests anyway, unless you never want to fly in Ishgard...so generally the best answer is to quest. There's absolutely no point rushing to 60 now except for epeen. There's no raid content anyway and the only available tomestone has no weekly cap...
