Honestly, the problem with logical fallacies is that people use it as an argument. (See the infamous fallacy fallacy). Whataboutism is great when exposing people's deflections, but terrible when used to shield yourself from any and all comparisons.

Ra-den is used as an example, when in fact Limit (another guild) discovered and first used this exploit of resetting the boss.

Then assumptions lke "they know most of the team aren't closely watching early bosses" to set them up as straight up cheaters.

Obviously, in the context of this conversation it is relevant that Echo in fact are not the only ones trying to game Blizzard. Everyone is. Why is it relevant? Because the entire post is based on this bad guy Echo feel.

Calling it whataboutism is in and of itself a deflection.
