until later when there is like 3 towers left in the game lol
and that is just one of it's weaknesses it has always had part of it's power directly tied to how strong towers are and that change while it would be a good start wouldn't fix that problem
perhaps it be better if you could use it to place a small turret which would zap nearby enemies or taunt an enemy turret/ monster to attack it
it's zaps would ground enemies for 0.25 seconds just to have it available as a disruption tool or something and deal minor damage,
if placed near an allied tower it would boost it and either increase attackspeed or shield it or something
would make it useful in all kinds of situations maybe then people would actually buy it
