Watch how you approach the topic of match fixing. You can speculate, saying "I'm not so sure about the finals, something doesn't sit right with me," but if you are going to outright accuse players of match fixing you need something more than your word.
TL takes match fixing/abuse seriously and as such there is a burden a proof when you are accusing players.
Banelings are more a one and done kind of excitement while lurkers create tense situations that last a long time.
Baneling: "Oh shit, oh shit, BOOM" or "Banelings all died and did nothing"
Lurker: "Shit, shit, shit awwww fuck micro awww shit he's holding, he's holding crazy marine micro awww zerg is holding but the siege tank is slowly pushing zerg back AWW FUCK DARK SWARM IT'S ON, ZERG BUSTS OUT AND THE GAME GOES ON"
I prefer excitement that lasts, know what i mean? =P
and baneling mines = hold lurkers so that's a wash imo
