I'm in agreement with the OP that the needle swung too far in the other direction. Unless you use a prebuilt craft or know what you're doing you could waste hours and hours in getting a manned flight to one of the other planets, only to find out you needed a few hundred more delta v to return safely and having all that time wasted - and this is personal experience. Much easier and dare I say fun to send a drone on a one-way ticket first. There's several solutions to this that have been mentioned elsewhere but I just wanted to add my impressions.
I'm launching a probe to Moho, using Mechjeb, get to orbit alright, transfer alright, looking good so I speed the game up.... ... and crash into the Mun.
