Due to the large mana regeneration it provides, it is excellent for many casters but especially those with spammable spells or persistent AoE effects such as Anivia,  Karthus,  Swain,  Maokai, and  Amumu. Note that the buff increases energy regeneration on energy based champions to 65 per 5 seconds (the base is 50 per 5s). The cooldown reduction granted is very useful for powerful ultimates with long cooldowns such as Curse of the Sad Mummy,  Idol Of Durand,  Stand United, and  Requiem. I just copied and pasted from the crest of the ancient golem buff page. I'd say some ppl just start at blue because its their "go to" jungle route, It lowers cooldowns and gets you lvl 2 immediatly. And with a leash, blue is really easy to kill.
