If you go for farming, or bunch of bosses that dont require fortress, then you leave it at 1pt, if you end up not using it.
Another change would be with really good gear, wolf companion curse starts to become less and less relevant, because you deal so much phys damage, adding that 1.5-1.8k from wolves becomes small % of your total output dps, and costs very large amount of points.
These points then could be technically invested into daedalus, or spirit guide for more ewd, but just 10 per slvl, so its not that great, extra defense wont be very useful, and it wont be always up with just 1 wolf running around.
As I said, for progress I was sticking to original build, beat uldyssian with it no respec, just at that point i capped 400 signets (then life goes to abotu 24k). Also getting void ring is easy with just standard build.
Technically everything can be done with very same build, except I would suggest respec for full vit healer for: witch and void final, just makes it considerably easier, and for laz different build thats bear tank combined with screaming eagle slow, damage is irrelevant in that fight, also ww is useful.
For farming, id go full str, 1pt fortress, and either stay wolf companion or shift those points elswhere, daedalus or spirit guide and more AB, there is several options.
For bossing that require no bear stance, same, except max lion stance. Just full dps, don't even need dr, use TU lion helm to get more. This works vs bosses such as: xazax, astrogha, kabraxis, zorun etc. Thats when you want farm trophy and do a lot of runs. With high damage astrogha is very killable with just iceburst, takes about 20-30s. Xazax can be killed in just 5s with su labrys.
