Traveling in WvW is tedious.
Traveling is going to be a bit tedious, and honestly it needs to take time to get back to the fight. Its bad enough with zergs just rerezzing the dead over and over, but giving them these tools to get back at you even faster is a terrible idea. How would you like it if the enemy that outnumbers you, that you worked hard to get rid of, came back smashing at your door even faster? Sure I wouldn’t mind if traveling was more “fun” but adding vehicles that “protect” you, just means they can use them against you.
Your best defense here is having a good offense, which also means travel with zergs or a party, its more fun with other players that you know anyways. Just make sure you are protected against people that take advantage of culling and other exploits too, that just ruins the fun when you get solo’d.
