High totem limit

I'd like to request/suggest a new support gem to deal with high totem limit. I have Ancestral Bond and it's a pain to cast that many totems all the time. Something like:

Can only have one active totem.
100% more damage per totem limit.

It's not unbalanced because you give a support slot, have less entities to mitigate monster aggro and you cannot have interactions like Ancestral Unity or Watchtowers.
