I'm a lev. 29 guardian, and on a rp server, so I intend to keep Kira with me at all times. I have found that the first and only fight I had a hard time with was the boss in the mission the defector. I have kept myself geared up with end. and strength and I have kept kira in the same gear. I have a few orange gear pieces, but keep seeing the defence levels on them not change much when I try to upgrade the mods on them, but in general I don't find the guardian weak. I have found my sentinal a bit on the squishy side and my counsilor just got to courasant, so i'm undecided on that toon. My only real complaint on the guardian is the lack of any inate healing, and as a result the long cooldown on medkits, as well as the fact i can't heal kira easily. If I could just give kira medpacks to use as well as have an ability to cut the cooldown on them even by a third guardian would be nearly perfect to me.
