I would like to start by defining Milsim as a play style.
True milsim (Military Simulation) is a very small area of paintball where the players attempt to use similar 'weapons' and 'tactics' as military... Tac vests, mag fed, and strict movement diciplin are the norm...
In this strict interpretation of the game of paintball an electro would be a big no.
Woods ball often sees a lot of people that are half way milsim and half way rec ball. they use tippmans or other semi milsim looking guns that still have 200rnd hoppers and such...many of these guns are equipped with E triggers or RT triggers capable of high and sustained rates of fire.
I see absolutely NO issue in using your electro in the woods! Why not? They are lighter, more efficent, often easier to shoot...They just don't 'look' the same...
On another note, If players are complaning about higher rate of fire issues, it could be two things.
1) a lack of understanding of how an electro can be programmed or
2) Maybe you are shooting more than they are even at your 10bps cap?
Either way, This issue could be resolved easily by remaining calm, polite and talking with the other players and working through their issues.
Who knows, maybe you will win some of them over and see more of them pick up an electro?
As a last resort you could always switch to pump!
