As players advance in the game they should be awarded with ever increasing land tiles to elevate their base designs. It seems that even with 130 land tiles you don't have enough room to build a stronger base and have enough room to keep attackers from sniping your base from the outside of your base especially with the newer hulls and the range which comes from the newer weapons.
Here are some ideas:
1. levels 50-75-- 130 land tiles
2. levels 76- 99-- 140 land tiles
3. levels 100- 125-- 150 land tiles
4. levels 126- 140-- 165 land tiles
5. levels 141 and above -- 175 land tiles.
If adopted it would increase the need for a player to spend more time in the game so that he or she could advance in levels.
I hope that anyone who reads this, please leave a comment or maybe add some ideas along with this, in the reply section.
