1. If forfeit/disconnect is done by the users then it should count against his/her tier.
Reason is some people just disconnect/forfeit on the first hole due to a bad start and some people disconnect/forfeit because they are losing in the 8th or 9th hole. If a user has forfeit/disconnect 3x in a day it should have a setting in the game to not allow that user to join. I have run into this issue a lot lately including legend players as well. The quitter tiers point should spread among those that are still in the game.
2. If forfeit/disconnect is done by the WGT server then it ok that is understandable.
3. Golf balls can't not change during play.
I think that you should be able to change your balls during play if you have multiple balls that are available to you. Example wood be your on your last ball and you hit it OB, Water hazard, lost ball you only have the option to buy more ball but if I have different balls that is available why can't I use those available ball instead it defaulted to the WGT ball.
Thanks!
