The other day Bran, Whim and I completed the Sorcerer-slayer deed in Mirkwood to upgrade the virtue JUSTICE.
So I was thinking, "Wouldn't it be nice if we all shared one or two common virtues and we apportioned a little time on Monday nights to keep those common virtue(s) up-to-date?" That would mean we have fewer virtues to upgrade on our own - plus it goes so fast in a group!
So I did a little research and there are at least two virtues that work for all classes - HONOUR (at max rank it gives 38 Vitality, 3,278 Resistance, and 923 tactical Mit), and JUSTICE (at max rank it gives 214 in-combat morale regen [the highest ICMR of any virtue], 259 morale, 510 non-combat morale regen). CHARITY and ZEAL are also good for all classes unless you are over the cap for physical mits (more info on stat caps here: http://lotro-wiki.com/index.php/Stat_Caps#Stat_caps ). And if you love RESISTANCE as much as I do, you might even consider CONFIDENCE (it has Will but is super high in resistance at 3,278).
So, let me know if this idea appeals to you and if so, I will keep track and add the appropriate deeds to our schedule.
