Planetstrike is obviously not intended as a balanced, tournament game. It is intended to be a fun, agreeable narrative style game, with winner and loser not as important as having fun. As such, an official FAQ would not be expected from GW (well, when are they ever). That doesn't mean the book doesn't need it, so here are my proposed revisions. This isn't how I play it, but these are just suggestions. I would appreciate feedback on this post so I can tweak the list and maybe make it official for my group.
Comms Relay: Counts as an artillery piece. Can be targeted separately unless it is part of an intact building, in which case a "Weapon Destroyed" result can take it out. Models don't have to be on the roof to use it.
Bastion Turret Weapons: Use a BS of 2 as normal, but if a occupying model is on the roof he may use his own BS instead (and may fire at a separate target).
Crash and Burn: If a Hit is rolled, use the arrow to show what direction it scatters but it will only scatter D6 inches (I feel that since you get 4 templates, they ought to be a bit more unpredictable).
Laserburn: The affected area is treated as Dangerous terrain afterwards (it's a friggin' lava scar).
Meteor Strike: Count it as a D weapon from Apocalypse (at 4 Stratagem points, it ought to be a bit more beefy).
Teleport Barrage: I don't like this stratagem. It is far too powerful. It should either cost more points or have a different effect. It makes it so a defender can't put any valuable units in a bunker. No terminators, independent characters, nothing as they don't just take a wound, they are removed from the game. It punishes small, elite armies like Eldar and Marines, while IG and Orks will laugh it off. It seems to me a cheap way to kill off very expensive models. I am not sure how to fix this one.
Imagine this- I have one bunker with 5 Dark Reapers plus Maugan Ra. If hit with the Teleport Barrage I would likely lose all but one or two reapers which would be several hundred points down. Another bunker has 20 Ork boyz. They would only lose about 3 guys, which is like 21 points or whatever. It's just so imbalanced I think it needs to be removed.
Edit: I thought of a way to fix it, simply state the models on the roof are not affected.
Other: Chaos Daemons may use the Blasphemous Broadcast, Euclidean Mindphase and Hellish Cacophony stratagems (since they don't get their own, I figured these fit in their theme, plus they all sound like titles to H.P. Lovecraft stories).
Chaos Daemons: Of course they can assault the turn they come in. For their deployment, don't use the rules in the codex, instead follow the Planetstrike reserves chart. I'd like a Daemons player to chime in on this one, especially on the normal deployment/reserves issue.
Like I said, I'd like some feedback on this, especially from Daemon players and those with a hefty amount of Planetstrike experience, as this is just a rough draft.
