Maybe in the default UI... but with a proper weak aura setup it's not hard at all. You have 1-2 Starsurges and 2 dots to cast on the move. Knowing when movement is happening is an encounter issue, not a 'Boomkin isn't easy' issue, and they have lots of tools to counteract it. Your cooldown requires no thought. Use it at the beginning and stack it with Lust, or use it at the beginning and use it again when they Lust at the last 30%. My two trinkets being damage proc trinkets means my rotation doesn't even change
