The Bad Mechanics of Teleporting and Shielding
First I want to say I like the teleporting and shield abilities in the game as they are needed for many things and help people. But there are few thing they are used for that really should not be possible to do in the game.
Problem: Teleporting next to your target so you can attack them in 10 seconds. This kinda defeats the whole purpose of having a guard tower and warning. Also make it not possible to send help to defend. It just something that the game would better off without.
Fix: After teleporting you cannot send an attack for 1 hour or ( X amount of time)
Problem: Attacking someone the instantly shielding so no counter attack or revenge can be done. (very cheap if done after teleporting next to your target)
Fix: After attacking anothers players base or troops you cannot shield or teleport for 1 hour. This would make you actually think about attacking......
Think these changes would make the game much more enjoyable.
