Hmm if you want fast tomes I think it is WP HM atm.
For Nexus do the grind its pretty fast after nerfs now... I do atm the zodiak quests after as I got war nexus gonna hand in for sch tho and made with the few dungeons/trials i do so far in 5 days to slight activity which is 1/3. I still hate the grind but the customization is worth it imo and you cannot get higher ilvl weapon unless you do Final Coils.
