In 6mans, you'll get constantly denied aggro (it becomes 5 man effectively, since as a guard you're not even doing too much DPS) and the crappy CtA and things are not worth it if you can just replace the guard with a pure DPS (although AoE spell effects; CtA/battlecry is pretty decent).
The developers are trying to balance classes out but it's hard for them since the game is so small and players finnicky of getting 'nerfed'. So, if you are not full into your guard yet, try to start a conqueror (excellent DPS, useful low CD bubbles, and most of all only in-combat rezz in game) or DT (the actual Main Tank of game).
P.S. Don't let anyone else babble anything else to you. I probably have the most hours on Guardian in the game and have been playing it since 2009, it was very powerful class at start then slowly all the power was taken away over the years and now it's junk class. People always try to defend Guardians in this forum but when I meet them in-game on their guard they're aggro is junk and they really don't know how to play it... yet they say it's "best main-tank class". So, overall stay far far away from this class
