The only differences are that far away from your region, weaving abilities between the GCD can be harder and force you to only single weave. This isn’t going to stop you clearing raids.

The other difference is cultural. EU makes use of macros to decide raid positions and uses auto-translate because of the multiple language spoken. There are other slight behaviour differences you might notice because of how life in the EU is not exactly like in NA. Different circumstances, laws, prevalent mindsets.
