Maplestory, ultimate adventurer brawler or spearman?

I'd say brawler has better mobbing skills. Though brawlers tend to have weak damage. If you want a good damage and decent mobbing skills then spearman. Unless you can fund your brawler, I strongly recommend you choosing spearman. Have you considered using cygnus knight brawler? It has better damage than the adventurer brawlers. I find it easier leveling with spearmans than the brawlers because it has better damage and more people prefer spearman.
