Yes, in any competitive game someone has to lose - although I say it's a waste of time for the other team not because they lost, but because they never had a chance of winning. It shouldn't be 'easy' to win a game where you're matched against other players. You are going outside of the queuing system to make sure you have almost no chance of a loss. How is that anything but cheating?
if you break it down, what does a full oQueue premade bring to the table that is unfair?
1. no bots
shouldn't this be encouraged? not an argument point unless you're supporting bots
wow has an in-game voice module that allows everyone to communicate. there is also chat to help coordinate objectives and priorities. my opponents inability to utilize the tools properly is not my problem
3. fully geared out players
i have literally run hundreds, if not thousands, of oQueue premades and not one had a gear or rating requirement. many players had no resilience and some were fresh 90s
4. gung-ho players
yes, the people that join the oQueue group are playing to win. shouldn't this be encouraged? why would you join the bg if you had no intention of playing to win? are the players queuing solo not intent on winning? why are they queuing?
personally, i would say the biggest impact on our opponents is their B&B factor. the bots and bads. those players with no intention of winning that just want a quick end so they can re-queue to grind more honor. this should be discouraged or at the very least, not penalize the other team for being more motivated
possibly the biggest advantage an oQueue premade has is #4. it's also the reason people love oQueue groups. they get to meet like minded players without being harassed as a 'try-hard' and coordinate to achieve the objective. it's a MUCH more satisfying game when you're playing with people that are trying, as opposed to losing due to your B&B factor being higher. this should be encouraged and blizz should NEVER cow-tow to the B&B crowd
