Played with Brits last night, Opponent kept his luchs out of AT nade range just fine.
Seems like a good change to me, it gives light vehicle players something to think about when playing brits. No more silly dives with 222, FHT or luchs.
Viability in 1's has been raised exponentially with this change, and to a lesser degree 2's.
Still not sure what maps I'm going to use the forward obs post on. Seems like a waste. I don't think I'll ever use this ability (even in changed form), it comes late, is hella expensive to use, and is destroyed pretty easily at the time in the game in which it comes.
EDIT: The cost of Air Resupply is way too cheap. MP cost needs to be doubled, or change reverted.
