Yea this is one of those questions that has puzzled gamers for years
Armageddon Patter- Too expesives for a Sentinel (KEEP them CHEAP) their armour 10 can easily be penetrated
Catachan Patteran- These are fine but only if your deep striking them in where they can get up close without being exposed to the enemy for long (I use that)
Cadian Pattern- Well if you figure it out the Str. of an autocannon (7) is the exact same thing as a Str of a Multilaser (6) For when you roll against a Space Marine army you need 2 not matter what. And since neither are AP 3 they always get their armour save. So for the sake of argument you get the same thing but more expensive compared to the Mars Pattern. And 9 times out of 10 you will me fighting a SME.
Mars Pattern- (same as top.) its the cheapest and 3 shots not too bad |
