1. Legion Castle is a goal. As are the classes that come in March (generally a new Dark Caster/BladeMaster + Legion DoomKnight)
2.1 Farm the PvP (brawl) trophies before buying UW. Then do the quests (the 40 kills for the champion shouldn't take long). Turn in, buy UC, sell UW for majority of ACs back.
2.2 Farm LTs from /evilwardage, r12, using
Lack of Four-Sight
2.3 Keeping a good stack (I prefer max, but keeping 5000-6000 is good), spend some on some items you like. If you don't have BLoD, grab the
Runed Legion Broadsword for 500 LTs
3. All of your goals include LTs which are RNG and Grinding.
