The bot argument is nonsensical, the value of buying an account and a boost is less than them botting a character to 58 in minimal time. The bots already exist as well, this concern is irrelevant. The reality, when it comes down to it, is that it’s purely everyones feelings on it, and nothing more. Trying to justify their feelings with logical reasons, how it could be bad for the game, but all of them have been disproven and made irrelevant.
It’s fine you don’t like it, because you don’t like it, but ultimately it benefits a lot of people, and it provides blizzard with profit on the the product which allows them to offer the product. Nobody will even consider the boosts when TBC is out, and you’re doing dungeons, raiding or arena, because it will NOT have a single negative impact on yours, or anyones gameplay, it’s merely affecting your emotions, which you can stop by accepting it and moving on.
