Necron technology allows many of its units to repair themselves at an
accelerated rate. This is reflected as the Necron ability in a unit’s
datasheet.

Units with the Necron ability that have been destroyed can regenerate.
Formations can return one previously destroyed Necron unit in the end
phase of each turn either on or off the board. In addition, if a formation
regroups on board it can use the dice rolls to either return units with the
Necron ability to play or to remove blast markers or both (e.g., if you
rolled a ‘2’ you could return 2 units to play, remove 2 blast markers, or
return 1 unit and remove 1 blast marker).  Formations off board are
restricted to using their regroup function to remove blast markers only.

Mosc, you could drop it in an email to me.

Version 1.9
…is the current version in Epic: Raiders 2.0. The Stormhammer
is only one major change to the list. After extensive play testing
the unit over-performed when compared to the other Super
Heavies. It had its stats changed from being a heavy shooter to
an assaulting SHT. This slotted the Stormhammer into a roll not
filled by the other tanks and is more reflective of the weapons
shown on the model.
The chart for calculating Leman Russ costs appears different to
eliminate the need to subtract, but the actual cost has not
changed.

While there were some concerns about flexibility and activation count, at the end of the day the Stormhammer was the only concern that really needed addressing.  I went through the threads and couldn't find anything else that required any attention.
