Hey Gentlemen,
I just stumbled over this thread.
Are you sure it is necessary to disable certain abilities in iron mode?
Because ... if you don't want to use a certain ability, you simply must not use it. Or, even better, you must not even learn it. This is ones personal decision.
But if they are all disabled when switching to iron man mode, they will be disabled for everyone.
Think about it ... if we now enlist all abilities, that would interfere with iron man mode for reasons of realism, I am pretty sure we would'n enlist the same abilities.
I for example don't like the instant boarding ability. I have no idea what this should be in real world. But, on the other hand, I like the clubhauling. It may not be very realistic, too, but I like it and use it, in iron man mode. I think any player should make his own decision about using or not using abilities.
Cheers!
