I hope:
#1: The abilities of the class stop using sorcery points. They generally can't compete with the benefits of metamagic, so they won't get used often, rendering the sub-class mostly moot.
#2: The hound scales in power as the character advances. A dire wolf with a low AC and 37 hps will get caught up and eliminated by a lot of area damage impacts at higher level with no real impact on the game.
#3: They fix the range issues. As is in UA, you can be miles away and drop the hound on enemies.
To be fair, even if it doesn't scale at all, using 3 sorcerer points and a bonus to grant the target disadvantage on the next spell is a pretty valid use of 3 points even without the creature it summoned. Suggestion "Leave your valuables and return home to think about what you have done."
