I used to play a lot of regular sniper when i was not playing Sadar.
It was my second most played spec.
Regular sniper is not very strong, but has ammo variations and pros and cons with each ammo type.
Normal ammo for Damage.
Flak being the one that you use to punish and slow Xenos pushing for marines to chase and kill them.
Incendiary basically to be annoying, maybe prevent some Xenos from pushing or help finish a kill, since its not strong fire, its mostly just annoying.
Needing to swap ammo depending on wich caste you targetting.
All of this can be blocked by other Xenos. Someone ran in front of your target? Good job, you didn’t hit it. (Defenders actually bunkering down to protect their boilers or other castes from you)
Now AMR, while only having one ammo type.
Does Damage, Slows, Knocks you down (Makes you drop any cap you dragging, cancels any ability with windup, aka: boiler etc). All in a single ammo type.
With the added ability to pierce targets and shoot behind walls, with added penetration to break said walls or doors.
I will admit, for me, it’s fun to play (even tho it’s just point and click), but i also see how annoying it is. I also have played against it multiple times, it’s extremely annoying and punishing from screens away. I have held and turn around long rounds just because i have this gun on my hands.
Queen trying to push? Nope, There goes a big chunk of your health.
Boiler trying to shoot? Nope.
Dragging a Cap? Nope.
Xeno in crit? You tried, but you cant block the shot.
You put that crit Xeno behind the nearest defense you could find and drag him there? Sorry it’s dead.
Marines unable to push pylon? No worries, ill just shoot the walls down and the Pylon itself.
All this while safe behind marines or cades and partially invisible(prone armor ability).
Is there even a reason left to grab the normal sniper? When the single ammo type of AMR can do the same and more, of both Flak and Regular sniper ammo combined. You only loosing on fire, but do you really need regular incendiary ammo?
The only real counters to AMR is 2 tile walls (wich, if they are Xeno walls you can also destroy mind you) and boiler gas, wich, you also often can see from 3 screens away and just focus the boiler to make his life misserable.
