Holy crap, there's a LOT of hate on this page. First of all, keep it civil. Seriously, there's no need to post like a **** in a discussion thread. Be nice or go away.
Next, the odds of a Gooey Bomb falling on you are way less than 100:1. First of all, they can't even BE in the first match. Second match, assuming they are the only thing turned on and nothing is banned (highest chance scenario), you have a 20:1 chance of one spawning at all, which is a rough estimate based off of how many items are in the available pool; this doesn't include individual types (like a piece of food, which has ALL SORTS of possible types). Depending on how the PRNG calculates item drops, the chances could be almost half of that (40:1). On top of that, you have to factor in the number of times an item will drop at all. In a 1v1 game, that's about once every 30-45 seconds, which makes it about 10-14 spawns (liberal estimate). On top of THAT, you have to factor in the chance of the item choosing a spawn point that is next to you out of all available spawn points (who knows how many per stage). AND you have to factor in the chance that you'll be attacking at the moment of the spawn. So, yeah, less than 100:1. And even so, the Gooey Bomb will only kill at ~88%, which is the highest kill % of all explosives in the game (save the Smart Bomb, but that doesn't count), so you have to factor in the chance that you'll even BE that high in %. Sure, 22% damage is nothing to scoff at, but it's not nearly as big of a deal as people are making it out to be. This is not going to be happening every match, or even every match the bombs are activated in, or even every SET the bombs will be active in.
Either way, this project takes the same stance that everything else in fighting games should have: until it becomes a problem in actual matches and tournaments, it will stay unbanned. If one Final's match is decided by a Gooey spawn, too bad. If it becomes an everyday occurrence, then we'll consider banning it.
Second, yes, the Team Healer can and will hurt your teammate. The reason for this is because Team Attack is on, and so it sometimes considers your teammate an enemy, which is also why Pit's / Dedede's FS's home in on your partner.
As for the HRB double team... yeah, that's the point.

If someone is unskilled enough to get caught and double teamed while the opponent has a HRB, it should, at least, make for a good match video.
