I've had lobbies where people called me a spammer for using a move once on a wakeup. As Sinestro you are an even easier target(My Adam, Hawk and Lobo have all gotten said abuse, how do they even apply it to Lobo XD), don't let it get to you, just relish in your wins, people that can't deal with losing will always try to justify their loss as not their fault, never let them, if you win it's their fault for failing to counter, never yours(that can be read entirely the wrong way, dont do that
).
Addendum: At a certain point this one lobby rallied against me. I then decided, oh you want spam do you? Lobo has never jumping d3'ed so much :3 About 3 hours later they all finally realised they could just leave the lobby and form a new one. They felt the need to point this out to me on mic.
RELISH in it. :3
