Suggestion: Separating raids in Duty Roulette: Alliance Raid or avoid specific raid

I consider myself a core player (in-between casual and hardcore) and had felt that there is a skill gap/time difference between the Ivalice Raids and the Crystal Tower Raids.

I've enjoyed and beaten the Ivalice Raids but playing it multiple times makes me feel stressed as a player; especially if it's often the selected raid for Duty Roulette. Luckily most of my party members understand that it's not really an easy/short raid so they don't mind me leaving/abandoning the party.

I have two suggestions:

• A feature that allows us to avoid certain raids.
• Splitting the Duty Roulette Alliance Raids into Crystal Tower and Ivalice Raids in the Duty Finder so players have a better idea of what to expect when they queue.
