Guild Wars 2

I’ve been a guild leader since october…or november 2013 and i always felt we miss some things.
The first thing i noticed we miss is the Guild Mail.
A Mail that can be sent by the leader or the members with the privilage,to all the guild members,how time aving would it be to be able to send a mail to all the guild members than sending one at a time.
Now about guild alliances.
Some time ago when my guild became important enough to be noticed,i met some other guild leaders,we played together,had fun together and because…life…after a while we didn’t have that much time to play the game so we wanted to merge the guild but we didn’t want to give up on the name of our guilds(mergining meaning everyone leaving a guild and joing the other guild) we spent so much time and effort to make our guild name noticed so in the end we didn’t merge.
The perfect solution for that would be an alliance and an alliance chat where we would feel like we are in the same guild,in the short time i played gw1 and some other games with alliances…i see no negative thing about it.
So,what do you think?
Would alliances and guild mails bring something good to the game,because that’s the point,to improve everyone’s experience?
