I've been testing it out in duels and its a legitimate threat.
As a pure summoner built both tanky and teleporting with the werebear / sw option, either dumping oak or lycan or how with remaining points, ravens can hit fast enough they'll catch people in teleport chases when they get interrupted a single time by bear/wolves, and all 5 ravens hitting someone deal 25000-30000 damage
and unlike the zoo that is going to constantly get nuked and resummoned, raven threat is omnipresent, they cannot be killed, so even if you're wiped of all minions its possible to just telestomp someone and they die instantly

>Ravenlore (could be +3 summoning / +3 grizzly helm, but ravenlore seems like a better package)
>Hoto / Stormshield (or spirit)
>Enigma
>+2 druid / fcr ammy, or maras, or +3 summon
>Trangs gloves
>Arachs
>2x soj
>resist boots or aldurs or w/e
>9x druid summon / life skillers
>torch/anni & life/res scs
>20 raven, 20 spirit wolf, 20 dire wolf, 20 grizzly
>1 werebear / shockwave
>0-1 poison creeper (it still does dick all with 1 point, like 6 HP/s for 8 seconds in pvp)
>0-1 cyclone armor (will only reach ~280)
>rest of points into your choice of oak, how or lycan, all valid options
