A lot of topics in this , PLEASE  respond to any or all of it.
Some mobs have been beefed up beyond what most can cope with. the Minotaur Capt. for one not some thing one would expect from a lower level mob . it is now both a  ANTI PET mob and a real hard mob to kill unless you are elite. this coupled with anti hiding makes Labyrinth  a VERY nasty place to go for a stroll.  would prefer  a new elite dungeon like the old black belt dungeon.  It also makes doing T Maps a lot harder when  a few of these spawn on you . a lot greater risk with no added reward  either in the chests or the labyrinth.

Next is Pet deaths and the 5%at loss. totally disagree with this for a few reasons.  first is it takes ALOT of time to find a lvl 30 then raise it up and breed it. do this for a couple of generations and you have a pet you want to keep forever. The problem arises when the pet say a donation elder werewolf or even lucky breed stats are OVER the cap. example 500 listed 300cap on a real nice elder werewolf. or a pet with 1200 str or 2000 life. that pet dies you either  LOOSE FOREVER the stats or hp  or spend a lot of time buying and making  potions to raise them back.  3 ways this can be corrected 1) remove death penalties. some mobs we can kill one day and not the next so this "don't want rushing in " is  kind of bs in my opinion. if we cant kill some thing in a try or 3 then move on and go elsewhere till we can. how do you know if you don't try > LORE does not show HIDDEN KILLER ATTACKS. so can not know till you try. 2) start by making all 3 not just 2 of the ADV vet kit potions permanent Couple that with when a pet goes over stat due to good breeding and luck >>the cap for that pet raises to that lvl. 
That way the real world $ you donated  for an uber pet or 2 does not  go POOF . 3) a ED result getting maxed stats to your pet refreshing everything to max (means raising sta cap on WW or what ever overstat  ed pets start with..

next are  a few bugs.   some times when NOT over wt  and NOT over itemed . things can drop to the ground upon death. even a blessed double axe. heard it but didn't believe till it happened to me 78 items of 175 200 of almost 600 wt and it dropped to ground. luckily had help rez up. and got it back.
some deco bugs training dummies and hitching posts both face the same way east and south directions face the same way.
BOWS with vortex strike > the energy vortex does not register as a pet . so be careful if more than 10 pet slots it can be considered an exploit.

VENDORS <> the rental contract..no idea how to collect.  Also a pain that  both parties need to be there to rent out a space. MALL MANAGERS <> 200 ed placed NPC would  do nicely <> place manager and have him rent out space and collect from the manager..

KEYS  hmm ok my list here is  just too long . from  an item having  a place in multiple keys to all keys should be blessed from the start to suggestions on keys.

feel free to comment and add.

Im cant say im a big fan of the pet losing stats upon death but that is something that was always around so i learned to live with it, the one thing i must say i am displeased about is that since they redid the caps on pets, all old donation elder ww that were 2 slots got nerfed, mine all lost isane ammounts of hp dropping them to the 2 slot pet cap, which i thought wasn't cool.
About the bosses that are anti pets well, its a different challenge and should not be easy for all, we sometimes need a challenge to better ourselves as players. Also, i like the fact that the world still as surprises for us, like the Captain Minotaurs you are talking about, if everything was predictable the game would become dull realy quick. And maybe im mistaken, but aren't minotaurs spawning on the high level T-maps? Not everything should be easy, again, its a new challenge!
Remember that nothing is set in stone and like all players, the shard evolves, the stronger players get, the stronger the mobs get too!

Please, explain "Anti Pet", is this where I risk my pet going wild if I go up against these types of mobs?  I hope not!  I keep running into the captains while doing tmaps.  They are left at spawn locations by other players.  I have died many many times recalling in to dig up my lvl 5 map, to find these nasty nasties waiting for me.


 The anti hiding is a nightmare with Minotaur Mobs as well.  My 1st line of defense is to hide.  I am not strong enough to go up against them.  Kill the anti hiding, for us weaklings, please?


I love the surprise factor, I even think these mobs are funny, but could they have a despawn timer of 20 mins when spawned at tmap locations, pretty please? So I dont have to keep avoiding tmaps?


I think donation pets shouldnt have the risk of stat/skill loss.  but thats my 2 coppers.  I havent gotten any, but if I donated to get me one/some, Id be pretty upset myself.
