Abuse for being a new player, any solution?

[Garlyle]

Using DF for any fight is traininng grounds. How else can you learn the fight?

Fun fact: In Japan, it's actually expected you know what you're getting into when you use the Duty Finder; and it's expected you use Party Finder to seek people out to teach and learn.

Anyway, sorry about the harassment you experienced. Titan Extreme in Duty Finder though is never a good time. It's tricky to clear if a DPS goes out for most groups; it's near-impossible for random groups of players to clear it if a tank or healer goes. As a result, a lot of players have very little patience for the fight (especially having been stuck on it for months due to how punishing it can be).
