User blog:TOMCAT1025/Problems with Liara in Mass Effect 3

I have a question - does anyone have a problem with Liara in the "battlefield"? Because, so you know I'm a guns type of guy and use tech/biotic attacks for backup, every time i try to get Liara to kill an enemy with a gun she just stands there and NOT firing her weapon and i had to keep pressing the command button (and when powers cooldown - i use it some where else) to get her to kill an enemy with her guns. If anyone can help me solve this problem - that will be great.
