Ok so I've been thinking about the long range cannon compared to the Sniper...
Stats(PLEASE correct me if there are any errors)
Long Range Cannon
So we can say
Across a range of 150
Across a range of 180
Heres the thing though,the bonuses...
In the average game I get about 8 turrets,with 2 being ice..
So lets do with the bonuses:
6 Long Ranges:
Speed-10+(6 x 1)=16
Range-180+(6 x 10)=240
With 240 Range the long range cannons quite literally cover the entire field if they are near the center...Problem is it's difficult to get to this point,I am trying though,and I think I may be able to make it farther with them than with snipers!
