I have been retesting the order of the green lady this weekend in universal battles and I have to say, all cavalry can certainly work under the correct situation. I got beaten by an all cav basilean list when i was playing my all hurscarl northern alliance army, in what can be described as hasting 2.0(die didnt help at all when it came to surviving the charge or counter attacking)
And then i ran my green lady against undead in a 2000 points battle with 5 redeemers and 2 brotherhood units, in a match that ended in a close defeat, mainly due to having bad rolls in relevant situation(when you get 7 hits hitting on 3+ and a 2 double 1 in a row you really are in a bad day)
But then i ran a more balanced all cavalry list, that added the order of the forsaken to the roster.
This was my list
Army: Order of the Green Lady
Points: 2000
Unit Count: 8
Unit Strength: 25
370, Order of the Brotherhood Horde
– Vial of Sacred Water
– Banner of the Green Lady
200, Order of the Brotherhood Regiment
200, Order of the Brotherhood Regiment
200, Order of the Brotherhood Regiment
270, Order of Redemption Regiment
– Maccwar’s Potion of the Caterpillar
250, Order of Redemption Regiment
250, Order of Redemption Regiment
260, Order of the Forsaken Horde
– Healing Brew
The idea was to build my army in two battlegroups, one with all the pathfinder units in the more densely packed with terrain side of the board, that is to say one battlegroup had the horde, the pathredeemmers and another unit of brotherhood juts in case, whereas the other one acted as a weak flank with just one of redeemers and 2 brotherhood units.
A unit of redeemers and the forsaken were left in reserve in the center of the field to act as a mobile interception force that could support either battlegroup. Plan went tremendously well, with both flanks pulling off a great kill count at the expense of only 2 orders of the brotherhood units, that acted ad chaff for my redeemers to pull off charges and the forsaken being able to pull of flank charges against enemies of both battlegroups.
I still think redeemers are not decent, they are exceptional, but indeed you cant spam 5 of them and call it a day, forsaken can be great too and brotherhood serves as chaff so your redeemers dont get charged before they can go all lethal. Think about it this way Redeemers are not 250 points, they are 175, since a unit of redeemers makes an inspiring mounted hero redundant(in fact its better than the hero since his bubble is bigger). For those 175 points you are getting a high volume of attacks and regeneration. there is simply no cavalry that is more cost effective in the game. True you dont get access to the lute like you do in a mounted hero, but i would definitely trade that of for more direct killing power.
