I had one of the worst matches ever (randoms, on Silver, Hydra, Collectors):
I'm playing with Quarian Marksman, a class i don't like but i'm trying out Marksman-Idra combo. At least i know how the play the class...
My team: Juggernaut, Geth... Engineer or Trooper and a Paladin.
The Juggernaut doesn't use his Shield, Turret nor does he use Heavy Melee to drain health from enemies.
The other Geth is just plain bad, dying constantly. I don't know his class since all he did was to use Hunter Mode. And die.
And the Paladin, he goes to melee, very ineffectively, has Energy Drain but no Snap Freeze, which is arguably the Paladin's best power.
They waste Medi-Gel on non-Objective waves. The Juggernaut used a Medi-gel when there was one enemy left and he didn't bother waiting for the other guy left standing to rez him.
They waste Missiles... on such things as singular Abominations.
We died on Wave 8, which shouldn't have been that bat (2 Scions, 1 Praetorian) if they hadn't wasted Missiles earlier (and if i had lived, died early, didn't use Medi-gel because i can't afford to waste them on non-Objective waves (have 3 left), they didn't rez me). We had two scions left as enemies but the Juggernaut and Paladin are morons and go to some corner without cover, and waste medi-gel rezzing each other... had either one of run to cover on the other side map, he could've slowly killed the scions...
I want a Lancer so bad!
Seeing it in videos, it sounds so cool and beefy and unlimited ammo and larger clip size, it'll replace the Harrier for me absolutely.
Harrier is stronger and more accurate, simply put better. At least if weight isn't an issue... and if it is, you're better off using pistols or SMGs anyway.
