Ork/CSM melee MC Vs Unique 100LP for durability and regen Vs 100LP for 40% lifesteal (or burn/poison). No much of a decision there. But I do use some of the M/C heavy weapons. Mostly the MC aren't worth it, but sometimes they are. We'll see what they do to them to improve the situation as they've already admitted they are overpriced
Meltas, Knives, Kannon, Lascannon, ZZapgun and the gravgun are the only ones that seem worth it to me to have as mastercrafted right now.
I very much adore my master-crafted tempest launcher on DR... but I can only sensibly fit it into a veteran loadout. The Tempest launcher is already expensive enough in the first place, let alone getting some decent armor in there as well. The lower heat gain is really nice, though. That one extra burst can mean life or death in many circumstances.
I'm really pissed off at the fact I spent $120.00 to get Relic weapons for all four factions, only to see these Relic weapons as being totally worthless because they cost +100LP more than standard weapons. 1. We get .05 less recoil for the Relic Bolters at a cost of +100 LP. On a standard issue Bolter we can add a 20LP mod and get same stats for 75LP less. 2. We get 25 more durability for Relic melee weapons for a cost of +100LP. We can get the same stats on a standard issue melee weapon for a cost of +20LP mod. Do the math. Can we pretty please, with sugar on top, JUST ... MAKE.... RELIC... WEAPONS... have the same exact stats and the same loadout costs as standard weapons? So basically they are SKINS and we're paying TO LOOK COOL not paying for special stats WE COULD CARE LESS ABOUT.
As far as Mastercrafted they're definitely not worth it. MC weapons should have slightly better stats all round. Ranged Mastercrafted: +faster reload +less recoil +takes longer to overheat +longer damage drop off +slightly higher ROF(if it makes sense for the weapon type) +slightly higher armour pen +shorter cooldown(melta, heavy bolter, autocannon) Melee Mastercrafted: +more durability +slightly higher Armor Penetration +moderately higher damage +faster durability regen
