How would you use Minion Dematerializer?
At first it sounded so nice: securing those cannon minions early, easily pushing one of the earlier waves in and then get some free pushing power for those mages that have some problems.
But so far they seem fairly unusable, the only thing that really worked was quickly demolishing a cannon minion before backing.
I tried it on Lux because you sometimes struggle oneshotting the ranged creeps if you don't build flat ap =>
but while the slight damage may do the trick if just as often didn't and again minions survived with 3HP
Having more waveclear might break some things but the damage is simply too insignificant too make a difference, when you are ahead you might kill them just as good without it and when you're behind chances are they are juuuuust not enough.
Personally I think the bonus damage should be increased, having "kill 6 minions instantly" is just not worth it when you could get a stopwatch instead.
