yeah but with max 5 CP a game, and knights CP going up, along with CA points going up on a couple Knights and hopefully Guardsman to 5ppm, the list that is the most popular right now (6x10 IG with HQ's, 3x3 Heavy Mortars, 3 BA characters, Castellan knight) would be 200pts more than it currently is.
When you look at it all like that, -200pts, +more cost to CP, -CP farm. If you had to use +3 more CP a turn while only getting 1 back, after 3 turns that 6 CP that are gone just from the 2-3 strats you use on the Knight every turn, not counting Re-roll strat and other strats like the BA one, you could start with 10 CP and be out completely by turn 3, before that wasnt even possible.
Given all that it will be a game changers.
But Aeldari is going to get a small hit too for sure, mostly DE, Grots, Talos, Ravagers, Dis cannon are all a possibility.
