3 ideas:
1) Widen the choke from the natural to the main, making it a little easier to scout/harass.
2) Destructable rocks from the main to the 2nd natural.
3) I was looking at the "bridge to nowhere" on the top main, and thought it would be sweet if that bridge extended out to the back of the gold expo with destructable rocks on the gold side.
Oh! Dynamic maps... is this possible? Can the bridge & rocks "materialize" at an arbitrary time ...10:00-15 min in game time? (Visions of the bridge flying together like a watchtower with Zel'Naga magic)
Something like that would add a new twist to typical maps.
Anyways, cool map redesign.
