I think it would be a whole lot easier for players to be able to buy or obtain a 4-person mount in game. It would be so much easier for everyone to be in one place when questing. I know it's not like Wizard101, but people still play this game and quest/farm together. I have almost 7 maxes in Wizard101 with only my life being 140.
I am trying to get on the grind with the story mode again in this game that only has a level 70 Buccaneer. I am attempting to do questing with my friends and we have come to the conclusion that having a 4-person mount just makes sense.
