Here's a few questions that I need answered

When a character occupies the Eleha'al vine does it count as hindering terrain and therefore grant hindering terrain bonuses?

Does the Lunge feet allow 2099 hulk to a) Move 2 squares then attack b) move his full movement, 2 more squares then attack or c) Neither. How exactly does this feat work?

Under the new giant rules does a character still need to break away when they are adjacent either 1 or two squares away?

thanks in advance

1). Eleha'al vine is an object and works just like any other object in terms of terrain and such.

2). In order for any character to move 2 squares and attack, they have to be given an action that results in a close combat attack. In order for 2099 Hulk to attack, he must be given a close combat action or power action to make a close combat attack, activating his lunge. He then moves 2 squares an automatically breaks away (he can't move his full speed value with leap/climb since leap/climb activates off of a move action and does not grant a close combat attack).

3). Giants no longer have 2 square adjacency. They just can make close combat attacks against figures up to 2 squares away, so long as they normally be able to attack them (no walls or such). So giants only have to break away against figures right next to them.

I'm just emphasizing the movement portion.

He could still use L/C with Lunge tto make a close combat action against a figure on a different elevation.

Adding to that last sentence...the figures have to be right next to them AND on the same elevation. A grounded giant is not adjacent to an elevated anyone. There would be no break away. (There'd also be no ranged combat restrictions either. )
