You sound like me, we like content that is easy going and relaxing that looks and sounds cool and is fun, super hard stuff ain't my thing either, though me and u differ on what we call hard, I still feel ya my lala bro.

When I first started out on this game in 2013 I never played an mmo and hadn't touched any rpg type stuff since Zelda a link to the past in the early 90s, I started as a warrior cause my friend chose paladin and warrior/paladin looked the coolest to me, I didn't even know a tank was or a dps, I just pressed buttons and stayed up front cause my xwife was a dragoon and my buddy was a paladin and I thought if you weren't in melee range you weren't hurting the boss, I thought healers were the ones who stood back and thought ranged jobs like black mage and bard weren't doing any damage since if they weren't up close, didn't know any of the mmo terms, didn't even know how to read the map till a month of two in game.

Reason I tell u this is you are similar to me and if noobs like me can do it then I have faith in you to do it as well, my advice is use jump potions if you want or lvl without em, whatever floats your boat, maybe learn this game on a dps first cause it's the least stressful role, I learned this game on a bard cause at first I sucked at tanking but I'm now good, unless your super dedicated to learning on a tank or healer cause ultimately play what u want, also ask questions and keep watching guides cause repition is good way to learn and hopefully one day we'll end up in a dungeon together, till then do what content u think is fun and keep learning at your own pace my fellow lala friend.
