Firstly, Mech does not counter a DM hugely, because a Pr0 DM vs a Pr0 Mech will be a very close match indeed in the opening rush. What usually happens with me, is I hang back until I get +3 att and ensnare, then i snare mech, maneuver Dark Orb around mech for a pseudo-block, all the-while attacking mech for 49 dmg per hit.
Secondly, If mech attacks DA then i have that much more hp when he decides to attack me. A smart mech would l1 the DA while it's trying to run away, either forcing me to move it back towards mech (thus giving mech a chance to kill it) or keep moving it away and hoping it lives. (also thus giving both siege tanks a chance to kill it)
but having the two on the same team is a very powerful one.
That is very, very, VERY true!
Volt also counters DM well due to avoiding maelstrom and being able to outstun her,
Volt counters DM majorly, unless DM has allies to back her up. (DM is a girl
)
Reason one, is because Volts l1 & l3 are mana draining whilst DM is mana-heavy.
Reason two, is because Volt Transforms (l4) into an unstoppable-uncursable-untankable meatshield of pure death
as does Mutant by manualing.
By the time mutant tries to manu attack l2, DM has moved away by then. Even if DM stayed in one spot, the lings spread out because they are allied to everything and therefore not attacking stuffs. With mutant's l3, the lurkers can get one synchronized shot off before dying.
I do however have a personal problem with mutant/summoner lings. They move way too fast and are way too small for me to maelstrom/ensnare efficiently. I usually manage to click on them 2/3s of the time.
None.
