Would (You) be interested in a separate server with JP rules?
From what I remember after a few days of playing when it released:
-All standard units and WoDs are reworked (most of them are dogshit now)
-Buffed versions of old limiteds
-All rouse cards get Prepare so they become cheaper every turn
-All realm mechanics have cooldowns (2 turns)
>Aequor can't use white/red stance every turn
>Caro can't heal with the furnace every turn
>Ultra can't annihilate every turn
(I didn't play chaos so no idea what they changed there)
