Guild Wars 2 game mechanics
While fooling around with Build Editor I saw some terms that were quite interesting. We've all heard about combos but how much do you know about them? Do you know how to create an effective combo? Maybe we could start working on some basic tactics if we knew some more about mechanics behind Guild Wars 2? I'm not talking about minmaxing, because I don't like going into extremes but I think it would be really fun if we could plan some cross-profession combos and try to execute them in game.
Another curious thing I've found are chains. It's interesting mechanic but there's one thing I don't get. I'll give you an example. Mesmer's first sword skill is Mind Slash, and it has two chain skills - Mind Gash and Mind Stab. How do I use this chain? Are they performed automatically, or do I have to press 1 at the right moment to trigger it?
And last but not least, the Wiki page. It's pointless to discuss all this stuff without it.
