Great game, but it does have a few issues.
1. 'over time' effects (like bleed, slow, etc) are too often pointless to train - the greater the range of the unit, the WORSE it is to train because the units only fire at the creep furthest along. Player needs to be able to pick either standard targetting and 'debuff targetting' - aiming for the creep furthest along *that doesn't already have that debuff*.
2. Logistics reduces the cost of *placing* units by 1%/level.. Leadership reduces the cost to *upgrade* units by 2%/level. You could reverse those percentages and Leadership would still save you more money on most levels than Logistics.
3. Let us see a unit's skill tree without having to place one on the map. The unit mouseover on the hero screen (and the hero hire screen) should show the skills available to the units.
Again, I DO really like the game, but it's not quite 'finished'.
