It’s unfortunate that Sniper Training doesn’t have some sort of built-in graphic or spell alert. Out of every hunter proc or passive, Sniper Training probably needs something like that the most. If it were up to me, I’d have it display something like a circular aura around the player’s feet that changed color based on its status (active, recharging, or expiring). Alas, we have nothing besides the tiny buff icon up in your list of buffs.
I’ve developed a bad habit of jumping and strafing as I DPS. My Sniper Training uptime would be atrocious without some sort of addon to help me out. Good uptime will be key to maximizing DPS. Perhaps one day I’ll get better at it and won’t need such prominent WeakAuras, but it is not this day.
There are several addons that can help you manage Sniper Training, the 3 most popular are probably WeakAuras 2, NeedToKnow, and TellMeWhen. I’m a fan of WeakAuras and use it for all my other stuff, so that’s what I’m going to focus on here.
