Less Memorization - More Reaction? (Trials/Raids/Bosses)

[Garlyle]

They can do it like the Ifrit fight during 1.x, a mix of pattern and randomness

patter: Ifrit do specific attacks during the phases with specific time between the attacks
random: you don't know what attack come next

That's basically exactly what Thornmarch EX is. There's X number of attacks that come out, with some new ones being added after the first revive. The only rule to it is that it doesn't like to do the same one back to back.

I know a lot of players who don't want to go back to Thornmarch EX unless they have to.

I'm not of the opinion randomness is automatically a good thing, but it's not automatically bad, either.
