If something is an unintended side effect and the developers did not intend it to happen, fair enough to argue against it.
But if they did intend it to be part of the difficulty of the game, even if only tanks have to face it...well, what? Do you think difficulty in any particular game has to revolve around what you personally dislike?
Just because you don't like something, doesn't mean it's a bug.
I mean, where does it end? If you think your in a position to argue away intended challenges, where do you stop? Which ones are acceptable to your sensitive palette?
And what of the thousands of others - what if they think they can argue this way, and what challenge you think is okay, they think is a big bad spoils their fun bug? Someone, somewhere might have their fun spoiled by what you think is okay - and as much as you think you get to determine what is a bug rather than an intended challenge, so do they. So it must be removed!
Eventually all challenge gets removed as there's always someone who's fun is spoilt by practically any challenge and you end up with...a themepark.
Oh yeah. Right.
