I propose the following:
Changes:
-Phantom Lance in the CWE list will be called the Shadow Lance
-Incubi (15pts)
+1 boarding modifier
Roll 2D6 and pick your result in H&Rs
-1 to enemy H&Rs against a vessel with Incubi
(this should be 15. It's only +1 to boarding and the other H&R stuff adds to their +1 H&R built in rules. These are budget space marines without the additional +1, planetary assault and exterminatus stuff, and without the leadership bump.
-Archon to 50pts, still with no reroll
-Aspect Warriors (20pts)
+2 boarding modifier
+1 to H&Rs, -1 to H&Rs against them
(my reasoning behind 20 pt Aspect Warriors is that they do no get the awesome Ld chart that the marines get, which should probably be more expensive than the SM get it for. Anyways, the SM and CSM upgrade is 35pts and gives them the upgrades I propose for the Aspect Warriors and also the chart. I figure that the Ld upgrade is worth AT LEAST 10 pts. Also, the Aspect Warriors do not get the Planetary Assaults and Exterminatus rules. At this point, the Mark of Khorne gives double the boarding value for 15pts, which can no only neglect the opponent from getting a +1, it usually gives the Khorne player a +1 (often the equivalent of +2). That's a fantastic boarding upgrade for 15pts. The Dark Eldar Wych cult is the same way. This is an additional +1 to boarding as compared to the previously mentioned Incubi but does not have the nice stacking that the 2D6 has with their +1, making the DE H&Rs very powerful.)
