NS2 is lack of support tools

NS2, is lack of support tool! This is my commnet about NS2. Yeah. It is popular, but without support tool it wont be easy for beginners to learn NS2.

To use NS2, we need to create a simulation script - which is in Tcl which is not taught in universities syllabus. 

To run ns2, we need to run the ns interpreter, through console.

To analyze ns2 result, we need to create our own program or use third party tools developed by others.
