Tl;dr version = the league has some obvious issues, but the excessive whining is mostly not justified and coming from scrubs.
The long version:
The POSITIVES about bestiary imo:
*all the stuff that came with 3.2 itself, so the ascendancy rework, sextant/bisco changes, uber elder etc
*interesting new league, which i think sounds better on paper than in the game, but with changes (that have been made and are being/will be made, has potential to be alright
*decent, though not the best mtx rewards from the league
*abyss in the core game now
*bestiary rares and legendaries being pretty common from my experience (unlike some whiners'), i seem to get 1-2 rares, sometimes even 3 in every map or every other map. Also seem to get a legendary every few maps, sometimes in every map. Once i got 3 rares + 1 legendary in a single map so i have no idea what ppl are on about when they say that they ain't common enough... like do you run 1 map per hour or something?
*spirit beasts would have probably been in the negative, but that got buffed... so should be fine now - ppl need to take into account that these drop in specific tiers of maps onwards and we just had the league start, so i dunno why they thought the end-league stuff had to have been done by everyone during week 2 of the league... like this is when you GET TO endgame, not when you're already there...
The NEGATIVES about bestiary imo:
*lots of micromanaging and going through recipes/the book/menagerie to use bestiary orbs etc which becomes annoying
*necromancy nets being a too rare drop imo, although you can do the vendor recipe of 3 t10 nets into 1 necromancy, but those ain't so common either, that you'd wanna vendor recipe them much
*encroaching darkness div card seems to not drop much at all, which is a pity... specially i can imagine for SSF players
*capturing is counter intuitive to normal PoE play, because you have to stop and try to net 1 mob, while it spawns tens of relatively tough champion mobs to kill you... that ends in death at times.
*beasttrading and all the categories/mods involved etc can be confusing to ppl that haven't put in the time to self-research and make sure they understand it (that's on them though), but it's still needlessly annoying
*bugs
A list regarding what i think of the various QQs:
1.Map sustain - dunno i have 0 issues with it, i was doing unmodded t11 maps just yesterday and several of them dropped 3 other red maps... if you're running alched maps you should be totally fine as per usual, not to even mention if you use zana+sextants+chisels+sac fragment+vaaling or any of those. I've NEVER had trouble sustaining maps and i usually thrive, not just sustain.
What people seem to forget is that some of the previous leagues were loot pinjatas and now that we're back to a more realistic gameplay, they are in awe, cos they got pampered/spoiled by the previous leagues. I mean players from back in the day will know that you used to be quite excited when you dropped any red map... yet now ppl are so spoiled that they actually expect to sustain like t15s lmao. Lower your expectations...
2.Alchemy orbs - once again, i seem to be fine... also if you lack them, then just trade some other currency for them, like...
3.Legendary and rare beasts - as i said above, i usually encounter 1-2 rare bestiary beasts per map and about 1 legendary in every other map, or once in 3 maps... sometimes even once per every map. If anything they're too common imo. I've encountered 3 rares + 1 red in a single map. Are these ppl running 1 map for 30 minutes or something?
Ppl with a fast clearspeed build can run 1 map per minute lol, even faster actually.
4.Also quite funny how some drama queens conjure up arbitrary numbers and magical statistics in order to make their point look more valid... a'la "99% of the POE playerbase is in standard and doesn't like the league"... lol oh really? xD
5.Also quite funny how ppl say that they feel like the first month of every league is a beta test... i mean GGG monitors things and makes changes accordingly. Isn't that a GOOD thing? I mean they release something new and check statistics and feedbacck and change stuff on the go... do you want them to just release leagues and never make any changes during the 3 months? It's to be expected with new content... you should know that. Just cause things get updated/changed during the league (a good thing), doesn't mean that the first version was some crappy beta version or something, stuff just got changed based on the feedback... what's wrong with that lol?
6.Also ppl with 0 challenges, who have clearly not had any personal experience at all and base their uninformed opinions, on hearsay from others (which is very often overexaggerated and misleading + subjective) should really just not comment on things. Stop parroting.
7.Most people don't check forums or reddit and just play the game, it's usually just some tens of whiners on some thread and people usually don't praise GGG when all is fine, so the only feedback you'll see usually is he negative one where ppl are whining, when they think something is not right. It's like 100 000 players playing the game and having fun (how much fun, who can say cos the league ain't exactly the best like breach) and then 50 ppl on some forum thread whining, making it look like EVERYONE is whining, just cos they're the only actual ones that bother to write in the forums/reddit.
8.The most hilarious thing of all is some ppl threatening to not buy supporter packs, unless the game is changed to what they specifically want. You need to adapt to the game not vice versa. Are you gonna go to a football game and demand that the half time is 5 mins instead of 45, because you ain't got time too lol?
Calm your tits ppl and chill :)
