Suggestions!

1) Speed-up button for co-op.
When you press the speed-up button, your co-op partners speed up button will light up slightly! Meaning the you're waiting for him also to press speed-up.

2) Un-equip button for heroes in a unit and to un-equip heroes themselves.

3) Look at the rather beautiful suicidal mode staring evilly at me....
I really want to do suicidal mode, and I think it is unfair that level 20 barracks is required!
Please find another way for people with-out level 20 barracks to play suicidal.
Maybe.... from PvP wins?
Or number of CPs?
Or nice warfare titles?
Or maybe by fame? (10 000 fame for suicidal mode)
Or by percentage won on insane mode? (90% win unlocks next difficulty forever!)
