Hey I started a few of the battles in Cool Ranch I've found them rather hard, I'm a level 16. Should that be high enough?
Sounds like you're not really looking for it to be challenging. There are many considerations to look at besides just your pirate's level. What is your Nautical Level?
Are you keeping all of your companions trained up near your pirate's level, or are they lagging behind at level 10 or 12? Are you using melee attackers charging in against ranged attackers who use Overwatch and Burst Fire?
What about your pet? Is it leveled up enough to be helpful? Have you morphed with other pets that have desirable talents and powers?
Have you gotten some good No Auction gear in your travels thus far? Are you playing in Avery Realm, so that other pirates are in the area to join in battle with?
All of these questions and more will need to be answered in order to truly assess where you are at.
