Why does it break groups up, to enter a group based-area where you would want to grouping to happen to begin with?
My friends and I always wondered why groups of alliance mates are broken up to go visit the alliance hall to receive the tree buff. It seems very counter-intuitive to break apart just to either meet back up to reform due to grabbing a buff.
In counter point, I can see everyone not being of the same alliance being removed, or why it might break up for them. However, when I'm in a party of 4 members from my alliance, we should all be able to go as a unit to grab it. It just is like.. weird. I'm sure this is not a priority due to bugfixes and balances, but it can't hurt to get this out there now.
