I agree with most of Alosso's thoughts.
I don't have a gripe with the trees, it's been pretty well documented on which trees you can go through with FBS off the tee. Then again there are a few that are problems (Olympic and Merion I believe) that you just have to work around and if you keep notes you'll quickly learn which ones they are.
My issue is with the drops/re-tees from water hazards. If I pull a drive left and it bounces in rough or hits cart path and then goes into a lateral hazard (think left miss off the tee on #11 on PGA Nat), I should be able to drop within 2 club lengths of where it went in, as it clearly hit land before going in. I don't even care that it would be in the rough, at least I would be hitting 3 from +/- 150yds and have a chance at getting up/down to save par. Instead you are USUALLY put back hitting 3 from the tee with no chance of par, and often facing a double bogey. I get what you're saying about the the "easy programming" Alosso, but they already have the still images of the course for where the ball went in (they showed it when the ball hit before going in), so should not be a huge effort (at least IMHO) to make a "drop zone" within 2 club lengths of that area. There are also water balls where they do give you a drop just back from the hazard, usually a creek crossing the fairway, so it seems there is no hard/fast "rules definitions" of hazards on wgt.
