Every time an "allied order" pop up i desesperate myself
I found very hard to play with friends for a couple of things:

In game chat
The fact of needing to go out for honor to chat with ur friends make doing a group very diffcult

No clan support
There is no support of any kind to large groups, althought play with random people against a well formed groups is useless...

Look for friends matches
It would be great to look for friends match and go into it, instead of be waiting for them to finish a game, establishing group, etc...

IMO improve play with friends would be and marvelous addition for the game in every aspect of it
