Guild Wars 2

There are a few possibilities:
Remove pets all together and apply the damage our pets did to our characters. Eg. us 60% pets 40% of overall damage output, removing pets allowing us to properly inflict 100% damage.
Require a 5 – 10point investment in to Beast Mastery to charm/use a pet. Before using this trait our damage output is 80% of it’s potential 100. After using this trait our damage is 100% of it’s potential 100, our pets inflicting 20% and us the same 80. This way with or without the pet, it’s damage is negligible only providing us with a small benefit. Why I do not suggest we inflict 100% damage before traiting is so that people still feel the desire to invest in this trait so that they can inflict maximum damage assuming their pets are hitting the same target.
Or allow us to permanently stow our pets.

Pets provide very little benefit. Although they do shine in certain situations, those situations are few and far between. Most prominently in open world PvE where our pets tank and we lazily DPS from afar. The idea is fun and interesting and I personally enjoy having a companion while roaming in world versus world. Unfortunately the appeal it brings to the table is mostly aesthetic and the desire to have a pal with you where ever you go. Which would be the same idea as me taking my cat for a walk… I’d love to have her with me on the go but in the end it’s going to shorten her life and slow me down.
