the first is more of a feature than bug... Unless I guess if you are trying to not level up?

I did notice the speed *on is no longer grayed out while not being leader, I haven't tried clicking on it thou. It could be useful thou. There were times back when team instance was still hard when I need 1x speed SOME of the time, but given that you have to grind it a lot, most of the time it's on 2x. So I had to communicate the need to team leader in excruciating details before hand. It would be preferable if this feature can be disabled by leader thou, just so that people don't press it in mistake (or two ppl trying to toggle speed at same time, might end up failing to toggle and miss timing etc)
