What's your favorite thing in the game?

[Alleluia]

I like doing achievements, glamour, fishing, relic weapons, PvP, and story content. I worked through all the side content in ARR before moving on to Heavensward, including all sidequests (both standalone ones and questlines like postmoogle, feast of famine, hildebrand adventures), relic weapons, sightseeing logs, etc.

I am now on post-HW (patch 3.4 content) though my long term goals are to get the High Roller achievement (the biggest grind part seems to be both cactpot achievements as they are based on time and randomness), as well as eventually the Big Fish title (I have all of the ARR big fish caught and am working through the HW ones now).

I commend you on getting the Big Fish prog. I'm finding those to be ridiculously hard. lol
