ur first sentence kinda confused me

well ddpt mg is around 55-60m
12m unslot.
if you could sell ur +10ddp saber for AT LEAST 43-48m(DEFINITELY MORE THAN THIS), you'd profit from selling it..and not unslotting.
in my opinion, just keep it...unless you love to pvp all day(see next part)
the only bad thing about DD weapons on left hand-since ur blade almost forces you to(which is why people use DD daggers on right hand)
is that in pvp, it is VERY hard to switch. you'd have to manually take out the right-hand weapon.
+10DDP glad is great in training though-you run high agi+more dmg compared to ddpt mg
