Last time I played there were 2 noobs messing around in a base doing things like shooting at the NTU silo and sniping the wall turrets, blowing gens with punishers etc. I kept killing them and then they logged off. I don't know if they ever came back but I felt bad for possibly running off 1/3 of the TR population that night
It's a fine line being an experienced player and deciding whether or not to just let the noobs go and keep them around or shoot them.
