i guess do all the quests you can, and keep doing dailys and bg's.
if u can multibox im assuming it would be quicker just to level 9 trials to 20 and 5v5 tho
If you have guild tabard and run bg's with guildys you will eventually get there. When i was in epic and was always running 4-5 man premades i was almost to Friendly after a month and a half, which means about 3 more to honored :/ just takes time........
before you do all that make sure you want to stay in that guild, cause it might be a grind. i had a lvl 19 honored with a guild and i wanted to got to another guild but it held me back for months then finally decided to move him. it sucked to start all over again but happier with new guild now.
