Can you win any secenerio ?

[Hawk Kriegsman]

The OP mentioned tactics so I'll go a little off topic and ask , How important is watching the replay. Simply saying, I use it 1% of the time. I know it will help but is it critical?

I am like you in that I rarely watch the replay. 

That being said there are times that I get surprised by unexpected enemy forces in areas I did not expect them to be in.

So I will finish my turn and send it to my opponent, then go watch the turn he sent me prior.  Sure enough you will see forces briefly as the dart from out of LOS into LOS and back out of LOS again.

The only way to see certain things like that is by watching the replay.
