@Ynna: I go full support in wvw and pretty much always get gold at keep sieges. I don’t know what the criteria are (damage to commander?), but I’ve never felt underrewarded.
And maybe I’m delusional, but having seen what Eles and Rangers can do to defenders on the walls…I’m not that jealous. They do a lot of damage which amounts to nothing. Even if defenders get downed, they’re back up in no time, and there’s not much actual effect for the outcome of the siege, in comparison to the people on siege equipment.
A great support Guardian, though, can keep siege equipment and operators alive, and keep a group from having to pull back from a keep. That can be the difference between victory and defeat…and you only get karma for winning.
So, basically, Guardians shouldn’t focus on the one thing they do badly, particularly when it is such an easy weakness to overcome. We can buy blueprints and become awesome in sieges; no one else can buy anything that makes them have the Guardian’s skills and survivability.
