If there are trainers out then just use them.
I'm not sure if you realize just how elitist and hypocritical your reply is.
You're saying that people shouldn't be allowed to enjoy a particular type of game if they are not capable of playing it as it is delivered.
Then you're saying that you need a trainer to enjoy a game that you want to play but isn't capable of.
Guess what, I envy people able to play DBH without a trainer just like you envy people able to play CoSMOS without a trainer.
