Which is my exact point
I said turret towers aren't the worst depending on how you measure
If you measure in damage no they aren't
If you measure in speed maybe they are not sure how fast necromancer towers at level 1 are
But you can't compare the two. You're comparing a damage dealing tower to a support one. It's like comparing apples and oranges -- two completely different things. You also have to take into account the cost-effectiveness of the tower. That is, take the damage divided by the cost. Consider the following below:
A turret is equal to 1.5 archers in terms of DPS when both are fully upgraded, but which costs more? 2100 for a turret level 3 or ~350 coins for 1.5 archers?
So in our example above, archers still deal more damage per cost than the turret. I don't know about necros but the description says the damage and range increase as level increases. You'll have to get a stopwatch and measure how much damage it deals (use healthtag mod).
