Guild Wars 2

Hello,

Recently we’ve seen the introduction of new healing skills into the game. Although not my cup of tea as a Guardian, it has been exciting to see these updates. I am under the impression that further (non healing) skills are being introduced, am I right in thinking this?
I was wondering why there might be a delay in these skills. Is Anet eager not to overload players with new skills all at once? Are the skills hard to come up with? Or is it more that time is needed to balance these skills?
So with that in mind, I was wondering how balancing issues have affected the implementation of new skills which players are hoping to see. It’s just a question which I’m interested to hear an answer to, maybe even some guidance on when we can expect further skills / how long it takes to balance new skills before they are made available in-game ?
