I see you’re new around here so,first of all,welcome to the forum my friend
And second of all,yes,it is most definitely worth using a drone!
The drone plays as your worthy support.Be it extra damage,extra heat or extra drain.
And yeah,what Betsy said is true.Sometimes it’s better to deactivate your drone.For example,I once died because my drone (on my electric mech) used a little too much energy,and so I didn’t have enough to fire and completely drain my opponent.His batteries were still a little charged and he shredded me xD…
But that doesn’t really matter,for 99% of the times,that will not happen;it’s just a one-time change in strategy that most probably won’t happen to you.The drone is very important overall.
