By using logic, There are meteor falling, you can see that you can't stack them, then golems pop out of meteors, if you kill them without letting them eat the meteors, then other meteors will pop and probably wipe the raid, then you should think : there might be a way to destroy the meteor, you will surely try things and discover that golems can eat meteors.
Also for Ice Fire and Thunder it's quite easy to understand, someone will automatically get hit by both and see that it cancel each others.
The only annoying part for T9 is the dives but after a few try and analyze of the situation you can see patterns and work on a reaction.
