i have a non obbed(
) 93 sb that i never use, so take the advice at your own risk...
as for boosts the first i lvled were str and vit and lvl 1 int boost(upped it when i had more to spare).
as for support i only use vit and sometimes str, even when using pixies i find vit better(i never use int). And use almost always str boost on my pets except for pixies int.
The ones i upped as soon as i could were breeding and dual summon which makes raising your pets a hell of a lot easier.
Also i upped claw cause some ppl look you in a weird way if your buffs are no good(maxed) from 80+ on i would say
i personally left creature mastery for when i had jps to spare since pets make good dmg even without much on it, so i didn't find it indispensable, though i have it at lvl 17 or 18 atm if i remember correctly
Creature control i have it maxed but it depends on how many good pets you have, cause if you have 3 good ones for example, lvl 3 is enough. And from certain lvl(50-60ish) filler pets on formation that are never summoned lvl really really slow so you don't loose much having them out of formation.
Energy beat is nice, since its the only spam skill sb has. Its good for pulling mobs at dp or while farming and yes at higher lvls skill it helps when farmin. I personally lvled it for pvp cause atm i didn't have a rp so when ppl were close to death they started running, and this skill upped worked really well for killing them at that moment.
Hope i wasn't to confusing
