since ARR is directly most similar to RIFT than anything else.
wrong but I will tell you to read my comment above..
Fates= a mix of rift + gw2
Quests= basic in mmo's now
Leves= dailys with more freedom so a mix between wow and new ideas
Instances= again standard MMO idea
Crafting/gathering= Mix between most mmos (craft list) with some FF original ideas
If your bent outta shape over fonts and animations than there is little to complain about companys use fonts for a reason there easy to read and have a "mmo look" to them. So no nothing is stolen only ideas used and implemented better than the games they took them from.
