So let me start by saying that I know a lot of people will disagree because they like to TNT rush - and I'm not trying to be rude to those who do - but I think we can all acknowledge that it is very OP... a little too OP in my opinion. So I want to try to suggest a few changes that will make TNT rushing less effective. Not all of the changes will be made together, I am just suggesting a variety so that we can try and work out the one which suits the players the best 1. Somehow nerf TNT: Make it have a smaller blast radius or take longer to explode. 2. Make TNT only available after 2 minutes or so of a game so that players have longer to prepare and defend their bed. 3. Make water and blast-proof glass cheaper so that they are easy enough to defend your bed with faster. Water should be 10 Iron for a bucket - no one buys water anyway - and as @Shamboman said it is too easy to just block it off. And glass could be reduced in price to 8 Iron for 4 blocks. 4. Increase the price of TNT so it is not so easy to rush players within a minute of the game starting. This could be making it available for 1 Emerald or 12 Gold. 5. (This one is a bit different) make a lower build limit so that players can't just drop TNT from way above your head.
