A few things I have noticed during my play time

[Lazie]

Endurance: Seems to run out too easily. Now my memory is a bit foggy but I don't remember this bar constantly being empty.

Feign Death: Now this occurred when I was in Plane of Growth haven't really checked it in other KoS zones yet. I am an Iksar monk level 60. In the Plane of Growth after a successful FD and aggro has been cleared by the FD, A Sylvan Protector would walk towards me and still aggro me. It took hitting FD again to clear the aggro on him. A few minutes later another walked over and aggroed me the exact same way. Again been a long time since I played this content but that doesn't seem correct. I never stood up after the initial FD they just seemed not to notice I was FD'ed and aggroed me as if I were standing.

Unlimited Antonian Javs with 1 jav. This could be a beta thing you guys are doing but one jav in the range slot stays permanently no matter how many times you use it.

Sit Aggro on the hate list. During our time in Plane of Growth, to pull the named we would have a bard just face aggro mobs so a Monk could tag the named with a jav and sit to draw it off of him. With just face aggro it seems the bards aggro overruled a jav and sitting by the Monks. Now of course any clicky pulls aggro off the guy, but he should not be holding more hate than a Jav/sit to pull it off of him with just face aggro.

EDIT:

Faction Hits- One thing I forgot to add. While in Plane of Growth it seemed all it took to take a faction hit was to be standing next to people killing mobs. Now it may have been standing next to guild/group members killing mobs and you would get a faction hit I was grouped and guilded with the people doing the killing. This was with me doing no damage to the mobs they were fighting. I am pretty sure I wasn't sitting either when this happened.
