I was wondering what you guys thought about the 2+ and 3++ save options for necron overlords. The war scythe , barge and maybe even MSS seem like easy choices , but the cost to go from a 3+ to a 2+ is kinda steep and for a 3++ it is really expensive.

This ties in to my tactic question. When do you drop them off? Do you ride them around on the barge as long as you can or hop out 1st good target you get for the charge? I have been doing the latter to mixed effect.

What your experience?
