I'm totally for this, I hope my opinion doesn't come across as arrogant and i certainly don't mean it to if it does, so I'm totally open to feedback from my comment; that being said basically, the way I see it is like this...
Based on a specific players level of roleplay (good or bad) it is normally heavily reflected on that person's character, the depth of their backstory, the uniqueness of the those two and the all-around effort and therefore the overall investment that they have in that character. So with that in mind, it normally means that the people who are serious about roleplay tend to be more cautious when it comes to expressing their character IG and therefore not suffering from the Big Dick mentality (not necessarily saying that it means not being hostile). so, the people less invested in their roleplay (which isn't a huge issue) would be the ones affected by this more so than the more serious ones in the community.
And with my first-hand experience with big dickers, I would definitely say the people who come across as the untouchable immortal super soldiers tend (99%) to be the ones who don't have a heavily detailed and in-depth character and backstory.
hope I kind of made sense.
*disclaimer* this is just my opinion and I in no way mean to say that either heavily seriously RP'ers and more casual RP'ers should be treated differently within the community. RP is there to be enjoyed and some enjoy it more than others and vice versa, for example, I would say I sway more towards the casual side of the spectrum.
