Fight Smarter, Not Harder. So stop using a tactic you would use for your character and use what is given to you. The limited skill-set really tell you how to play as the character.
Off-tangent story time:
This reminds me of the time an old guildmate raged on how hard G2's Ciar/Nature(?) dungeon where you RP as a wolf. He was in the dungeon for 12 hours (probably an exaggeration) unable to figure out how to do it. Then he spend even more hours on the boss battle. No matter how many members of the guild said to use counterattack against the boss, he insists that he is using "counterattack" by hitting the boss after attacking (what the hell?).
