Guild Wars 2

So, i’m fairly new to the game, and I like spvp quite a lot, I have been playing it as a meditation guardian, and I like it, but I realised that retaliation was the thing doing most of my burst kills, so I tried to make a build based on that, for spvp, so far it has had a weird result, i’m not quite atacking that much anymore, i turned into some kind of unatackable suport class, because if people atack me, I just pop some block or retaliation and boom, they are harmless, or if not harmless, at least hitting themselves. But anyways, I’d like some opinion of more experient players. Feel free to call me anything bad you want, not like it is gonna reach me anyways.
