The Real Problem with Parsers

[Egnasya]

Try to look from different angle. End game raid like alexander savage requires everyone at the peak of their job.

Actually I don't think you can put it that way without some restrictions. No doubt it is the case in the first weeks when most groups will be composed of players that hover around the maximum available gear available until that point. The high end raids are no doubt balanced to be hard for such groups, however as players continue to clear the raid and upgrade their gear, they will naturally overgear it after some time, before it is replaced by a new raid. In turn, minor errors in playing rotation or encounter are more easily forgiven, not everyone will have to be at the peak any more.

Even the parser isn't officially released, ppl will keep using 3rd party parser. And you can't tell them to not doing that.

You can. Remove combat log, declare ripping data directly from the game bannable offence and see that through. It's just a matter of how you go about it.
