I don't know how to quote multiple comments so please forgive me for the lack of context.
I think there are too many scenarios and variables on this issue for my single line comment to be correct, so here are some of the things I have in mind about this in general:
When I said "under performing" in quotes I meant it in a relative sense, I was mainly alluring to the players that have enough numbers for the content but are not as high as other, better performing players.
I didn't mention savage content, but obviously the amount of skill gating on content by players depends on the difficulty of the content.
"That which can be asserted without evidence can be dismissed without evidence." - True enough, even though it makes for a bad argument because if everything required evidence then I would required evidence that your quote holds truth at all times. I believe that it was obvious that the more people that parse or have parser, the more likely that this scenario will occur, I don't believe this is a far-fetched hypothesis. The assumption that everyone that wants to/will use parser is already using them, then there is no point to add an official parser because all the people that wishes to use parsers are already using it.
Players are not usually dropped in savage content, at least not in Typhon. I don't have a static so I only ever do Savage/Ex with pugs and usually parties just disband instead of players being dropped because of the Japanese culture there and there isn't a good way to shift blame to a particular player to drop. Ofcourse if you are in a static then its fine and if you are using the parser to look for potential recruits I'm all for it, however there are no limitations on the usage of parser and it can be exploited, especially along with fflogs to hurt the more casual player base, even outside of savage/ex content.
