I think adding more importance to "secondary" features like IFF or ECM and whatever its called could be interesting. Not just as a passive feature but rather a actually actively usable feature on the battlefield.
Could spice things up... not just making a cross and having passive attributes. For example the spy drone we saw in the trailers.
On the other hand I hope they keep stuff like BattleMech-Tasers out of the game. Thats rubbish. But giving the player the ability to actually play around with sensors would also give smaller and faster mechs a real chance.
