Bot on, I say. Macros can enable you to throw actions very quickly, which can look like botting. There are addons that help manage cooldowns, which also can look like botting. Never admit to using a bot, i.e., don't ever go on record as being a botter. Most guilds appreciate the high DPS as A1I3n said. They really don't care how you manage it. And if people are watching you too closely, find another guild. It's your game after all, and nobody should be telling you how to play the game YOU pay for. You're the one running the risk with the bot, do what lets you enjoy the game.
