you are INSANE for getting this worked up over SHITHOUSE, the BRICK OUTHOUSE character. This is literally a thread titled "SHITHOUSE"
Shit-posts are very funny and absolutely have their place, If anything, your absurd seriousness over this further reinforces the need for more joke characters.
I understand that it might feel like an exploit, but I would counter you with the idea that if you recontextualize, it can also be a way for a player to augment their ability and make it better than it was before, at the cost of an item slot.
This seems like intended gameplay, Are you saying that you feel it is overpowered and therefore imbalanced? or are you saying that there is actual buggy behavior and something not working correctly?
Which the game really only does with lash and the fliers. Holliday also does a lot of aerial movement but there is nothing to scratch a long time tf2 player's itch for rocket jumping and air strafing
I am determined to keep Shithouse on the front page of hero suggestions until it gets enough traction for it or something similar to make its way into the game.
