I've noticed that whenever a studio is developing an MMO that features action combat (i.e., faster-paced combat that's more dependent on positioning, reflexes, and mouse usage), it acts as though it's developing the savior of the genre -- even though action combat is nothing new (just ask Dungeons and Dragons Online or Age of Conan). Instead of seeing it as a revolution that will bring us out of the supposed dark ages, I look at it as a different style of play that some prefer while others shun.
Both have their pros and cons. Hotbar combat allows for quick access to a wide variety of skills, levels the playing field for those of us old fogeys who aren't so tight in the reflex department, and focuses more on strategic thinking. However, it's typically slower and not as visceral as many non-MMO video games tend to be. Action combat, on the other hand, is certainly more in-line with its non-MMO contemporaries, with exciting pitched battles at the expense of time to think and a more limited selection of input.
So for today's Leaderboard, we're going to tackle the grand ol' staple of MMOs, hotbar combat, vs. the action combat upstarts. Will reflexes or brains win the day? Cast your vote after the jump!
