As we all know 11 Paladins, Draigo and a Librarian can be a total pain in the back side-weather it's hammer spam, the flying Storm shield or simply the Psycannon rain.
But don't lose hope!! There are gaps in their lines and it can destroy them!!
and here is some examples:
Sledgehammer to the hammer: obvious one is sometimes the simplest-have a nastier unit and/or hero to sort them out, mainly Thunder hammers and storm shields, lots of Powerfists/Klaws/Tentacles (if such a thing exists)
Sure they may dish out loads of nasty hits-but trust your invun (specially it bein a 3+) and make sure you always aim for the paladins-for you should know-a fist to the face counts as two for combat resolution-so killing 3 paladins outright is 6 on the res, and if all works out, the paladins will lose solely out of combat resolution and will flee (Draigo's fearless but his mates aren't muahaha)
And once that is successful you begin sheep herding him out of the battlefield (for ppl who don't know-Space marines cannot rally within 6 of a enemy unit) And then that's approx 1000 points destroyed by 1 unit and they're dynamic leader
My Guns are bigger then yours: Some ppl don't have combat units that can challenge grey knights or in fact any other marine elite-but they'll have better guns, generally fusion blasters, meltaguns, fusion guns, Blasters, Shok attack gun, Demolisher cannons,the list goes on, like any other model, all it takes is 1 shot to kill a model outright, best use of these guys is to have a full unit armed to the teeth with S8 guns, this helps us ensure that Draigo can't protect all of them. and this works even better when you got someone nearby meddling with their leadership and make them flee when they "Can't take the heat" :P
If they're much smaller after that, the mightiest threat is now minimal, or better yet if you can mess their leadership up and make them flee, the power of sheep herding.
My psyker is better then yours : They love Hammer hand, for it grants them the power of the Incredible Hulk. a unit with a libraian, draigo, techmarine and 10 paladins can make up Strentgh 9 squad (10 for Draigo) but like all other marine armies, they need to pull this off first, and that's Why the Emperor made Psyhic hoods and Runic weapons.
Having a Psyker there-with either his hood, weapon or Runes, he/she can destroy the squad's main combat strength and render their combat skills inadequate-Who would love to see a Rune priest, sitting 24 away with a long fang squad laughing as their friend in the Dreadnought bashes allot of Paladins left and right and the Priest there rolling 4+ to nullify their hammerhands?
So there you go to ppl lost in frustration or lost in confusion-ideas for ppl to try. Hope this helps and is interesting to listen too-Now go forth and ram those halberds of theirs right up their...........
