I think it's awesome for you to give them your thanks. I wish I could remember the names of those who were patient with my mom. She's 65 and normally does things solo or she had me and a friend run her through a dungeon on our capped characters in WoW.
Of course that's not possible in ff14 but everyone we've gotten in duty finder has been really patient and helpful. They've even took the dungeon slow to give her time to catch up.
So even though I don't remember your names I am very grateful for the kindness and patience that have been extended to my mom.
