Oh and make sure you have your Wisdom pumped up as high as possible. I think picking it from the Druid list is the only way to get thorn whip from spell sniper.
Yeah, I thought same, so I am going with 16 WIS from the start and will go +2 ASI later on as well, by level 12 probably. The spell is situational so I won't be pressing hard for it from the get go. Thanks for your help, I'll consider a bard dip for one of the companions.
