I've been mulling about Eldar holofields and their Dark Eldar counterparts lately, and I'm fairly unhappy on how they are implemented.
On the low end, against most normal-skilled people, -40 / -20 to BS grants them nigh invulnerability. On the other end, against a PC crew stacking bonuses >100, it often seems ludicrous. Especially the -20 vs macrobatteries seems completely pointless and only manages to cancel out the range bonus and the Rogue Trader helping out.
Has anyone found any workable changes to reduce this massive variation in efficiency, or have any ideas that don't involve lots of extra rolling? Right now, I'm tempted to just reduce 1-2 hits per weapon component instead of reducing BS.
