Yes, which will in fact proc wind striker. fun stuff. Also good to set up cliffs with ball/chain and stuff.
yes it will...I use to lift an opponent champ, going into a chasm and cleans the trsnporter for an instant kill
Personally, I think Lift should lose the "This champion's movement costs 3 AP while target champion is Lifted." It would then be useful as a catch and pull relocation mechanic in addition to windstriker combos (which are difficult given that SP only has 1 Windstriker Unit). Regular AP costs for movement wouldn't be out of line with other relocation mechanics, like pull, which is 3 AP for 3 squares of movement. It's AP cost (currently 1) could then be increased to 2/3 to limit the threat range of the ability (i.e. with a 1 AP cost, an enemy champion 5 spaces away could be relocated 5 spaces). However, the ability should lose its insta-kill potential, imo.
