Ogemaniac, you're making a lot of assumptions without any real grounds for those assumptions.
1. You assume that emni often tank heals.
2. You assume that Living Seed provides a *much needed* heal. Most of the time when Living Seed's heal procs on a tank, the tank will be high enough on health that the proc wasn't anything close to life-saving. There are a select few fights where a boss mechanic will nearly 2-shot a tank (and Living Seed is actually useful in those situations) but in most cases LS is just meter padding.
3. You assume that Rejuv is little more than a meter padder. There are a lot of times that Rejuv does little more than snipe heal what direct heals might otherwise have picked up, but there are just as many (if not more) times when without the hps of Rejuv, raid damage would become overwhelming and people would die.
4. You assume insulting people is a good way to make a point. =/
