Hello everyone!
I started playing
WH40k a while ago and have some orks on me with whom I do quite well in battle (won a 1250 pt. tourney last week

) and started thinking about getting a second army. My friend is the one who introduced me to
WH40k and he's collecting 2 armies at a time so I have about 1500 pts in all of my orks and he has about 750 eldar and 750
SM. I was thinking about
CSM, Tyranids or Tau. I thought of those races because of 1 or more of the reasons below:
a. They look AWESOME
b. They are very resillient (unlike orks)
c. They are very shooty (unlike my orks)
I want to pick something which looks awesome, is fun to play and is very unlike orks so I can try something different. Please comment and help me make my choice by argumenting etc.
Thanks in advance

!
