Lvl 53 Mage Fire Pet, what's the point?

[NPC]

Water pets are the best DPS, but Earth pets can be invaluable with the huge HP's and rooting. Having a tanking earth pet can save you if you over nuke or someone over pulls. If your not worried about agro Water pets all the way to 60. All i ever used was earth, the 49th level earth pet is best soloing, even at 60th level I still use that soloing. Why? It only costs 200 mana, with foci can have up to 3500 hps. At 50th level you med back 200 mana a minute. The higher level pets cost twice as much mana to cast have fewer, almost half the hps in some cases. Plus Tash and earth pet root can be quite powerful in some zones. Water pets are lower end of hps, but they will out dps all the other pets, so best in groups.
Also, I still use 49th level earth pet because the Quest Foci do not work on pets above that level. So the 49th level pet w/ foci is better than the higher level earth pets without Foci. If you get any epic foci, then go with that of course. Till you do, 49th level earth pet is best. FYI- I do not believe monster summon can use foci, so they are garbage. If you dont know what mage foci is, Wiki it up son.
