Hey Everyone 
I really would like to see that there are optional Passives for Attack Units and your Defense.
f.e.:Defense - Mortar: Frost-Rune (If Enemy unit takes damage - 5 sec -10% movement)
Thunder-Rune (if Enemy unit enters the red Circle - Enemy Attack Speed - 10%)
Fire - Rune (mortar projectiles leave a small flame area ... deal a bit of dmg)
Attack - Mage: Frost Shield (Mage gains a Frost Shield which absorbs 100 hp, if he drops under 20% life)
Polymorph (get the ability to polymorph a non-targeted nearby canon)
Blink (Blinks away if a trap was found)
::: So you can choose one of them:::
Another cool thing would be a Stealth Class, which attacks non-(defense/th) buildings. It only gets targeted if he is nearby a torch. But it would be nice if we get more torches then.
Thx for reading and have a nice day
