There's no requirement to activate on off-board formation that I've ever seen.  The only requirement is that if you do choose to activate them, then that activation MUST include a move to take them onto the board.
Actually, there's no proviso anywhere for not activating formations, regardless of their position on/off board.
There *is* a proviso for what formations in "reserve" can do, but that's something in the "Tournament Scenario", not the core rules.
And, reserves are defined thusly:
Quote:
Units kept in reserve must either be aircraft, or be going to enter
play in a transport aircraft or by teleportation. Reserve formations
entering play in aircraft or by teleportation should be placed aside
with units that will enter play via planetfall. These formations are
not ‘secret’ and your opponent may inspect them at any time.
...
Formations that are in reserve may not carry out any game functions
or use special abilities they may have.
Aside - This would seem to answer the rallying Space-Marines-evaced-via-Thunderhawk question: No rallying.
Now, the common assumption has been that units in portals are "in reserve", but the Eldar rules don't use the word, but consider them "back on the Craftworld".
It's a *good* assumption, but is not spelled out in the rules, and I think most people do regroup off-board formations or Eldar formations that fail to come through Wraithgates.
If we declare things waiting to use portals as "in reserve", it would mean they do *nothing* while there, no rallying, no alternate orders, nothing.  Only able to move out of the portal or stay put.
Now, I don't think we want that hard a restriction on the Necrons... or they'd never be able to rally off-board!
So, what shall we decide?
