I've always been up front and honest about what I have and have not done in coil. For the most part, they just want you to have relic+1 and a myth piece or two. Most have to explain their strat at the beginning of each tier since there are many different ways to do the bosses (especially t2 and t4). Stacking for rot, passing the whole time, and what order to kill the enemies in for t4.
