The combination of IWT + CTM, basically opens up melee teams.
You could do it before, especially in PvE play.
But these two combine for an amazing tool, which opens up a lot of previously unviable teams.

The effect is not perfect.
While the technique might be a science.
Using it in play is also an art.
You can spam it at times, or selectively press the keys at other times.
You will have to deal with runners.
Occasionally the screen locks into a slow constant spin, which right clicking anywhere on the ground fixes... but nothing else will fix.

Still, it opens a lot of doors, and is a very welcome tool to play with.
