The number of negative and neutral reviews indicates that there continue to be risks associated with punting. Furthermore, within the last few months we've had assaults, robbery / theft, attempted blackmail, etc just within the EM board, so the risks extend beyond a disappointing punt.
Although information-sharing on here and gathering information / research from elsewhere yields better information, these resources are also available for degrees of abuse by those who seek to deceive, exploit, etc. The additional scrutiny and sharing of information also adds accountability and reduces impunity for those providing poor service.
On a more positive note, being able to discuss and share information on good experiences and WGs is a bonus. Although even the best and most professional do occasionally have off days.
The bottom line is that where people, personalities, individual differences and preferences, changeable personal circumstances, etc, etc are involved, there will always be the potential for significant variation in experiences.
