Interrupts?

I had a question about interrupts. To be a good interrupter you have to know the skills from every class that really need to be interrupted right? So, how do we keep up with all of the new skills/classes that get added? I mean, they aren't even keeping the same names for the Factions versions of Prophecies skills, so how long will it take before the list of skills to know is too long? Won't new people eventually decide that there's too many skills and they shouldn't bother learning them or even attempting interrupt builds? Am I anticipating far more chapters of Guild Wars than there will be? Just though it might be an interesting topic for discussion.

Well most interupts are used against heals or rez. Obviousely there are other skills that are wise to interupt but the main block will be healing/protection. When new skills are added if they are better they will replace the current standard skills used. If not the old ones remain. Because of this there will only ever be certain select skills that people will use. Obviousely people will try out new builds with new skills but the majority of people tend to stick to pretty similar skills meaning you only need to know the standard skills at that time.

The more you play PvE the more you get to know em. The more you get to em the more obvious they are when PvE use them so you can occasionally end up predicting it and interrupting it almost before its started. Same goes for PvP, more you play it the more you know what skills people need for certain builds so you can pick em off easier.
