I played in my game store local monthly tourny yesterday and actually made it to the #1 table in the last round. There had not been any rules questions at all through out the day and the players were great, no complaining or negative attitudes. ( Setting the feel of the day)
The player across from me pretty much had the Blood Angels Razorback/Predator spam. So his army consisted of 9 tanks total. During his movement phase I noticed that he would move one tank then go ahead and try to move another and in the process would go back and move the previous one. Kinda like jockying them around like in a parking lot, making sure they had clear lines of fire and so forth. I have ran into this myself when playing alot of vehicules, there isnt enough room to move them around considering terrain, etc....
So I went back later and looked at the rules and on page 11, first paragraph it states "Once you have started moving a unit, you must finish its move before you start to move another unit. You may not go back and change the move already made by a previous unit"
I guess how petty about rules, and rules like this should a player be? I didnt get the win (placed 3rd), but I think that I really kinda let em slide a bit.
