Farseers down to 2w. As of our current understanding, roll on tables. Also, runes of warding nerfed (who knows how badly)
Means you don't get to choose your powers. If you can't choose your powers, you can't use army builds which rely on having certain powers. This just adds up to a big ol' nerf to farseers.
PLs also get nerfed - lose EW.
What these rumors add up to are nerfs to units which were already not good, or not good enough.
The only way this list would be ok is if the power table had fortune as a primaris power - if fortune still exists.
