Soloed Titan EX yesterday as a PLD (313) though I think it was done by a WAR back in Heavensward, it's good fun and I'd recommend to anyone. Gaols hit for about 13-16k and you have a chance to self heal before each phase. CD through mountain busters to reduce healing needed.

Attempted Garuda EX, failed 3 times. I couldn't get the adds dead before the check, as they become near invincible once they get close to 'Ruda. I got Sapurna down to about 15% and Chirada a bit less. I think you could do this if you had high burst to destroy the adds before they reach her but it would be difficult.

Incidentally, I also solo farmed T4 the other day (the earrings are super cute). I'll be doing some more soon so I'll get back to you guys
