My group is pretty open to Unbound. We have made a house rule to reward "bound" players. For any bound army you may choose your WL trait one of two ways:
- Roll trait, reroll on your chart if you do not like roll #1
- Roll a d6. Pick any WL table you have access to and use that trait
Players must decide which of the 2 options they wish to use before they roll. Most times it lessens the chance you get a crappy result (like Adman Will vs Necrons or Tau...)
Honestly I haven't had Obj Secured play a huge role in the games Ive played. Maybe 1-2 times. Most times the formation bonus I run is better (Necrons/Space Wolves). I haven't faced any super cheesy unbound lists yet. I faced a guy that ran all SM dreadnoughts. Another guy had 10 Lone Wolves and the rest Dreadnoughts. I partnered with a guy last week running all Greater Daemons. Skaarbrand, Fateweaver, Belakor and 2 LoC + his unbound Nurgle CSM vs 6 Imperial Knights w/ 1000pts of Blood Angels. Both sides knew what they were facing ahead of time and the game was very fun.
