I think the biggest thing about being lied to is that it's very insulting. Then from that it makes it harder for you to accept the liar's mistakes, because they lied. If someone says it's their first time in Coil, Titan HM etc. Then it is much easier to forgive their mistakes when they miss a silence or get hit by a landslide. However if they've lied about being experienced, not only will you be annoyed because you'd expect better from them, but the feeling will be amplified if it's obvious they've lied.

If people are asking for experience, please don't lie. Yes, there are parties out there who only want experience. But there are also those who will be fine with teaching you the fight.
