Hmm, unless the "Random charge lenght" means something along the lines the "leaked 6th" had:
By random this would mean that:
- Units that charge 12" cannot do something else (shoot for example)
- Units that charge 6" can do something else (like shoot first)
- This would be negated by the assault weapon / Pistol / relentless rules, leaving rapidfire and heavy (and possibly some new weapon type) to be able to only charge 6" after firing.
Even tho i know "random" usually means x-amount of D6 to determine stuff in 40k TT, that would be the only way i can come up with that wouldn't f*ck up the game totally for assault units..
Eldar units (and orks with waaagh) for example would have 6+d6+d6 as their charge range, i bet that players would love the challenge to overcome bad rolls to win ..I mean, i like random, but 8"-18" between the range units can assault is alot. Thats 60" worth of random move between luckiest and unluckiest player on an average 6-turn game
/EDIT
Oh, and about the allies. I wonder what allies and based on what situations / fluff would IG or GK/Inquisitors be able to strike a deal
GK: Could they be allied to any other force save for the demonically tainted? Or to remain the most purest force - no change to ally at all?
- GK strike force strikes a deal with tyranid mastermind (or whatever it was called) to strike down the demons at "Sector X", both factions benefit, 'cos the nids agree that chaos tainted stuff tastes bad and gives 'em gasses..
Inquisitors:
-Malleus: Forgot what these guys loath
-Hereticus: Funny team up with chaos tainted traitor guard
-Xenos: Funny team up with orks
- Point being, each inquisitorial force hunts for one particular enemytype, and more often than not are willing to coop with the operatives of the enemy other than what they are hunting. This would leave to a situation where each and every inquisitor would have its own set of rules against all possible matchups ..And what if player took two different Inquisitors knocking out the possibility for any allies :P
IG: Command squads teamed up with (rumoured) bs4 S5 AP5 30" rapidfire Firewarriors on a 4+ save (talking about improved guardsmen platoon). Oh, and you dont feel sentinels provide enough firepower? Well, take a couple of suit squads, that ought to solve the problem..
The team ups would be really troubling, and even the slightest overlook at some point would leave to absurd combos (6 squads of purifiers backed up by 9 leman russes and 9 Vendettas)
