if i have shield on the marauders wont go down i find. banshees are a pain in the ass as in single and especially in MP there is hardly any abilities that can down a barrier.
if your playing sp with CoSMOS i recomend max hp and no reload and spamn them down while you have allies or yourself using warp to rip the barrtier off slowly (stay at range though)
in MP since you won't be using a CoSMOS (or if you are you should be banned) use a krogan sent for shields/melle distraction, quarian engi for rocket sentry and 2 other of player choice and spam the hell out of a banshee or if someone has rockets to spare use a chakram rocket launcher. i have lucked out to use 4 a round and with banshees as bonus point targets its the best use ever
It would appear that it could be that the shield code maybe connected to several enemies in the game. But if you use the black widow sniper rifle and disruptor ammo you can take them down easy with a few shots. Four at the most if I remember right.
nice to know. i suck with sniper so i only use for the occassional pot shot when i have the shot lined up a mile away. unfortunatly for me i use garrus (loyalty) and liara (GF) so 99% of enemies i line up garrus takes the shot or liara has used ingularity to ruin the shot anyway.
lol yeah I had that happen a few times. But mostly position them on wing positions and once you see the switch arm and shoot!
