The best possible option is no concede actually.
Agreed. Coming from HoN, one of my first gripes with Dota 2 was no concede. However, after playing dota 2 for 100 or so games, the quality is much better without a concede. Ikuu is right, a concede would be thrown up in every single game (like in HoN) ,the second a team loses a fight past 15 minutes. If you didn't comply with the whiner he would afk and try to annoy the shit out of you by spamming concede votes, and the 1-2 holdouts would get flamed to no end.
The DOTA mentality is a lot different, most games I play, we keep fighting until the end. I can probably say 1/4th of my wins wouldn't be wins with a concede, as DOTA is a game of lows and highs, your mood swings wildly in both directions--and a concede gives an easy way out for the lows. The few games that are a complete wipe, you all agree to sit in well, type the ""gg no defend" in all chat, and the game should end in the next 10 mins. Sure, they might well camp you for 5-10 mins, but that won't go on forever with a raxx down.
Maybe just increase the size of the well and the damage of the fountain to demotivate well camping, but that's all.
If you want to concede, take the abandon. You get what, 2-3 a week?
go away, i liked him before he was flavor of the month
I can confirm that my buddy Icefrog is going to give the morphling to Gyro, N'aix, Clockwerk, and Alchemist (after much persuasion). Lycan and sf will get buffs as usual.
Valve allows people to call early GG's and has a kill switch in pro games.
I try to treat everyone with the same amount of respect, I see no reason why 5/5 people cannot come to a consensus on whether or not to surrender, while they allow this in pro games that have way more on the line than a solo queue game.
The problem with the very presence of a concede option is that the 2-3 defeatists that lose 1 team fight will bully the team into conceding. They will feed, afk, troll, bitch, whine until you hit that button. Their attitude essentially forces the holdouts to give in. "OMG GUYS I DONT WANT MMR CUZ PPL WILL FLAME ME." Yeah, concede will be even worse. Freakinchair is right, complete stomps will be over in 15-30 minutes, the games where you're down yet have some antipush and a farming hardcarry will linger on. I remember me, procarbine, and hyuna were in a game where we were down something like 40-10 in kills. We took one of their raxx and would have won the game had hyuna not trolled and basically intentionally fed 5 kills in a row near the end. We even had a 5k+ gold lead I believe. That would have been a 15 min concede, no doubt.
Like I said, you want to give up early? Take the abandon. Valve gives you a few a week.
