Then someone kicks it and it dies because of it's AC 11 and 19 hp and you fall prone and waste your 2nd level spell.
The stupid wolf has better AC and can deal damage and trip as an action or help as a bonus action.
The beastmaster's pet is weak but it is way better that find steed's steed.
It's just a horse for a 2nd level spell.
Not really. Again, the steed is intelligent and acts independently. The stupid wolf literally does nothing unless you tell it to - it cant help as a bonus action. You have to trade out an attack to make it attack, help, etc. The horse is less accurate, but deals more damage since it gets to attack again if it knocks the target prone with trample. Also its prone DC is 15 vs the wolf's 11. The steed will also tend to have more HP for a decent while if your DM rolls, since you can keep cycling steeds until you get one near max, then continue summoning that particular one.
The linked thread also conveniently ignores two weapon fighting, colossus slayer, sharpshooter and great weapon master, and its math is off since he grants the wolf an extra +2 damage for some reason (its 2d4+2 at base, so 2d4+4 at 3rd level, not 2d4+6 like he assumes).
Lets not forget you threw away your colossus slayer and other actually good class features to have a slightly better dog, which anyone can plunk down 30gp for (and presumably also acts independently). The paladin gets the steed ON TOP of the other stuff. Find Steed is the icing on their cake. The wolf IS the beastmaster's cake. It shouldn't even be remotely close which is better, but it sadly is. The fact that its debatable shows the subclass needs work.
Also, again, the ranger is a jerk for continuing to bring poor trusting animals to get fireballed. If the steed gets "killed" it really DOES go to run and play with the other ponies on a farm upstate (mount olympus or whatever) until you throw another 2nd level spell to resummon.
