2 things you need to be aware of in priority :
1/ You can’t be permanently transformed it’s about 66% uptime
2/ It drains mana like crazy, prepare to chug A LOT of potions
Now that we covered that, let’s jump into class synergy :
Chaplain doesn’t have any synergy with big doggo, only “usable” thing would be the knockback resistance for when you transform to make sure you don’t get interrupted.
Dievdirbys can help you have more uptime on wolf form thanks to CD reduction statue, so there’s that
Oracle has some good stuff, Divine might that’ll make Lycanthropy lvl 6, which means +10% in damage and critical rate. Arcane Energy can save some mana for the first seconds of wolf form
Other than that it’s a really good class for filling your downtime/helping party
Paladin is decent too thanks to really high CON to make you tougher and Restoration who’s getting along well with Lycan’s regeneration. Also has some filler CDs
Plague Doctor could be used with Healing Factor, it would mean if you go under 50% Wolf Hp, it would heal you back up. Movespeed is really nice too
Kabbalist only use i can see from this class for doggo is to drop a healing tree and transform in it, to heal all the missing HP from lycanthropy. You also get Ein Sof to make you a really tanky doggo.
Miko for now doesn’t have good synergy, but will soon get changes that’ll allow her to have a decent crit rate buff for most of the wolf duration … Maybe worth considering, still unsure.
Exorcist/Inquisitor Put those together as they don’t have much synergy with wolf but have decent filler CD to toy with when you can’t be a big bad wolf.
Yes Thorn is pretty good
