2) They mentioned Range indicators as a likely possibility.

3) Unit descriptions in tooltips just seems like something you're not going to need after about 10 matches and are used to the roles of the units.

4) They've also mentioned possibly increasing the queue depth so you can build more units at a time. I would be interested in knowing if there will be mutually exclusive upgrades as well, but I'm not sure there will be. The manual has a bunch of singleplayer and campaign information so it doesn't seem like it's just for the beta version. It is odd, the last time I heard, Larian was saying there were 60 upgrades, but this version only has 39. Maybe they were counting Dragon upgrades as part of the 60.

5) I'm not sure enough to comment on this. The hunters seem a bit weak to me, but I'll try them some more.

6) There's already a cost for spawning in, and I'm not sure that a penalty for dying would improve the gameplay. It sounds like that would encourage retreating from a fight and letting your units hang.

7) That's pretty true on a lot of these maps, although Juggernauts have the longest range in the game, and can hit anywhere on a map with the Imp Buster upgrade (although it doesn't seem to do a lot of damage to structures). I hope the full version has levels where there are bridges so you can send land units across and sea units underneath, instead of them being restricted to one side or another. The restricted areas you can move in water mean that naval battles aren't as important as land or air ones.
