Rhino is a great and fun merc to have...until other players use it against you
I get that Rhino is supposed to have a large amount of health, because its a fricken Rhino!
But the fact that it can use its minigun at anytime is very annoying
It can obliterate anything in its path and destroy enemies who stand in its way
It is very difficult to kill this merc due to its large amount of health and overpowered minigun
Not to mention that it can get a perk that reduces the overheating time on turrets and miniguns
Whatever tactics you want to use, it won't work well
If you try to flank the Rhino from behind and shoot him, you wont stand a chance because hes just gonna take a few hits before he turns around and shreds you to pieces.
The only way to kill this merc is using range.
A good tactic would be either using a sniper or any grenades that do large damage such as Skyhammer's airstrike
This way, you won't get damaged too much and you got a free kill!
