This reminds me of my first experience with a high level character leveling a lower level character and spoke English. She told us the future of our classes, and was brutally honest. I remember it like it was yesterday. I felt doomed, I stuck with thief because Spiderlily (SpiderJerusalem on neogaf) made it look so cool. I later noticed a lot of my Thief role models were different classes. Hogashi (ffxi gaf shell member) was still thief, but he became a bit grumpy with the advancements of the class, and maybe loved Thief/war too much. I spent a day trying to show him the benefits of assassin, and how it changed EVERYTHING. Good times.
I'm happy I stuck with it, though I probably would have gotten so much done if I leveled bard. No countless hours LFP, no being left out of BCs which were a good source of gil (I had stacks of beast seals, and kindred seals. One of my final acts in the game was letting someone use my account so they could spend the seals). This time, if I play, I'm leveling the bardiest (FFXI bard) support class, something no group wants to be without. For fun classes, I'll do those later.
