Watched the replay since it's relevant to this suggestion and honestly, I am very surprised Omni or cloudgnome w.e couldn't kill this guy. I mean, I can definitely see why builder stall can be bannable but this.. this wasn't even a real bad time shredder, it's just a defenseless demon running around the map using his nether warp periodically.
When I think of builder stall, I assume someone really gold fed with egg items, gold towers, buffed walls and lots of teleport staffs which by then, as aRt)Y stated, is the titan's fault for allowing such a builder to acquire that much gold. Honestly, this demon didn't get gold until gp hit which was roughly 5-7 minutes after this whole thing begun, maybe sooner. Meaning, his only way of escaping was by nether warp and nothing else. An equipped level 10 titan vs a 0 gold demonologist.. who's the winner in the end? Sure it may take a little longer than him just running up to the mound and dying but it's no reason for someone to be banned over.
There's also somethings to consider, especially in this replay, a titan can acquire a lot of necessary items to counter this type of stall from a builder more than a builder can acquire the means to escape to begin with. Looking into this replay, I was able to notice some things;
-Titan had a maximum of 4 minions and during the wall-eating of the base above euro, why not take the minions with him? Easy nuke bounce off the summons if not himself.
-Throughout their encounters, why not take an eye of the ocean? If the titan can afford msog, he can afford a 5g item. By the time demon builds a shelter, 4 fruits and a worker to debuff the eye, titan/minions could already be closing in on him.
-During demon's 3rd stall, roughly when GP hit at the shops, why not take a wotw to counter tp? Better yet, why not sell LE and get ethereal mirror? No survival items needed in that point of the game.
My point is, when stalling occurs from a builder, the titan should think of ways to out-smart the builder rather than sit there and go ''Enjoy ban, just lose, quit stalling!!'' I mean, with that much talk, the game could've already been over. Is it annoying? I'm sure it is. Can you win? Of course you can. Shouldn't take more than 3 minutes depending how fed you are.
Edit: (Response to
@aRt)Y 's post) I mean, if you let a baser outsmart you for 20 minutes
and able to get up a base...... no comment.
