Basically, why should we invest on making a tower when we could allocate that 1 population points for making a more powerful, more mobile, and more useful archer units.
Towers compared to archers are
-cannot be used in assaults, tourney or missions.
So what gives? What does towers have to offer? I agree they are useful in the beginning, when you are still in the process of training archer, but afterwards, archers are so much better.
A. Make them more powerful that archer or atleast as powerful, perhaps let them be manned by archers, thus gaining from hero upgrades of archer units. Maybe give them a 1 range advantage from archer units.
B. Allow them to be stored in storage so we can upgrade them slowly and compare the maxed towers to an archer units.
C. Allow them in assault/tourney/missions... maybe give them a wheel so they can be moved 1-2 squares.
