Maybe some one with experience can tell me i realize that nameks are the " healers " of the game, but the poco summoner are they more of a dps spec? or are they just a buffer/healer with pets? whats big differance between the dende healer and poco summoner?

the healer plays the role of a healer....(obviously) and the summoner plays the role of a combat class. they learn more attack moves and stat buffs instead of more powerful healing skills.

The Poco Summoner just gains two attack skills. The rest of their role is to summon minions and buff. But yeah, they move away from the healing aspect slightly.

if u just wanna be a pure poco, dont upgrade the healing abilities,

if u wanna solo, there is a hybrid build where u can invest some points into heals and rest in the damage skills
