One, if it is part of the game intentionally it is not an exploit, and two, who cares how other people play a non competitive game.
Yeah, it's an old trite argument and the answer is always the same: I honestly don't give a shit about how they play their games, I care about how their design suggestions affect MY gameplay experience.
If I'm offered a better option in a game I'll take it, especially when "maximizing your potential" is a big part of your gameplay loop. Which doesn't mean I can't have a poor opinion of how a given choice affects the balance.
If half of the weapons dropped in game would insta-kill anything with a single hit and the other half would turn out to be useless, I'd be justified to think it's shitty design even if "I'm not forced to use any of them".
