Now that some of the changes for 1.3.6. are being revealed, I have an idea for another group. So without further adieu, here's the group.
Knight - Press the Attack! w/ Encouraged Aim, To Glory!, Gather Your Resolve! Standard cookie cutter build here.
Swordmaster - Suicide Hybrid DPS - Full DPS Sovereign - Ether Dance, Whispering Winds, Great Weapon Mastery - Tactics are Focused Offense, Great Weapon Mastery, Ensorcelled Agony and Potent Enchantments. Use Nature's Blade for blade enchant.
White Lion - Take Primal Fury, Cull the Weak, Force Opportunity, Pounce, Lionheart, rest up Hunter. Tactics are Lionheart, Brute Force, Flanking/Pack Hunting, and Loner/Pack Synergy
Slayer - Take Deep Wound, Short Temper and Shatter Limbs. I don't play a Slayer, so I won't give all tactics, but use Short Temper in there.
Warrior Priest (dps) - I don't play a dps WP, so someone else will have to comment on that one.
Healer - any class
The Knight provides critical bonus to the group, some AP, resists, and CC. It is Knight's job to clear Guard off enemy targets.
The Swordmaster provides some burst DPS, Nature's Blade, and recast time reduction. The Knight is providing critical bonus, so Balanced Accuracy is not required. Nature's Blade is for the buffs and debuffs, especially initiative since that swings survivability and damage massively in your favor. Also Whispering Winds is there for the recast time reduction for Lion's Fury and Shatter Limbs (and Deep Wound if so inclined.) Also, the SM debuffs spirit for the White Lion's Lion's Fury.
The White Lion uses their new Force Opportunity to armor debuff opponents for the Slayer and Warrior Priest, but the White Lion himself will be using Lionheart for damage with the presence of the Swordmaster.
The Slayer is the heavy damage of the group, especially with the large armor debuff from the White Lion. He also uses Shatter Limbs to slow down the enemies' ability usage. With Short Temper and WW up, this has a 10s recast, equal to it's duration. Also with both up, Deep Wound can be spammed for 25 AP.
There are two tanks in the group, so one of the healers can be DPS. With the White Lion around, the best choice is a Warrior Priest, although an Archmage would not be bad either since the SM is debuffing spirit already.
I find a group only needs 3 support (tank/healer) to be effective. Using 4 support reduces the groups effectiveness too much for me unless some of them go DPS. This group has 4 support classes in it, so 2 are going for DPS to help balance the group. This is assuming this is a scenario party. Rules are very different in warband size engagements.
Let em know what you think.
